DETAILED DESCRIPTION

FIG. 1 shows an example air bed system 100 that includes a bed 112. Thebed 112 includes at least one air chamber 114 surrounded by a resilientborder 116 and encapsulated by bed ticking 118. The resilient border 116can comprise any suitable material, such as foam.

As illustrated in FIG. 1, the bed 112 can be a two chamber design havingfirst and second fluid chambers, such as a first air chamber 114A and asecond air chamber 114B. In alternative embodiments, the bed 112 caninclude chambers for use with fluids other than air that are suitablefor the application. In some embodiments, such as single beds or kids'beds, the bed 112 can include a single air chamber 114A or 114B ormultiple air chambers 114A and 114B. First and second air chambers 114Aand 114B can be in fluid communication with a pump 120. The pump 120 canbe in electrical communication with a remote control 122 via control box124. The control box 124 can include a wired or wireless communicationsinterface for communicating with one or more devices, including theremote control 122. The control box 124 can be configured to operate thepump 120 to cause increases and decreases in the fluid pressure of thefirst and second air chambers 114A and 114B based upon commands input bya user using the remote control 122. In some implementations, thecontrol box 124 is integrated into a housing of the pump 120.

The remote control 122 can include a display 126, an output selectingmechanism 128, a pressure increase button 129, and a pressure decreasebutton 130. The output selecting mechanism 128 can allow the user toswitch air flow generated by the pump 120 between the first and secondair chambers 114A and 114B, thus enabling control of multiple airchambers with a single remote control 122 and a single pump 120. Forexample, the output selecting mechanism 128 can by a physical control(e.g., switch or button) or an input control displayed on display 126.Alternatively, separate remote control units can be provided for eachair chamber and can each include the ability to control multiple airchambers. Pressure increase and decrease buttons 129 and 130 can allow auser to increase or decrease the pressure, respectively, in the airchamber selected with the output selecting mechanism 128. Adjusting thepressure within the selected air chamber can cause a correspondingadjustment to the firmness of the respective air chamber. In someembodiments, the remote control 122 can be omitted or modified asappropriate for an application. For example, in some embodiments the bed112 can be controlled by a computer, tablet, smart phone, or otherdevice in wired or wireless communication with the bed 112.

FIG. 2 is a block diagram of an example of various components of an airbed system. For example, these components can be used in the example airbed system 100. As shown in FIG. 2, the control box 124 can include apower supply 134, a processor 136, a memory 137, a switching mechanism138, and an analog to digital (A/D) converter 140. The switchingmechanism 138 can be, for example, a relay or a solid state switch. Insome implementations, the switching mechanism 138 can be located in thepump 120 rather than the control box 124.

The pump 120 and the remote control 122 are in two-way communicationwith the control box 124. The pump 120 includes a motor 142, a pumpmanifold 143, a relief valve 144, a first control valve 145A, a secondcontrol valve 145B, and a pressure transducer 146. The pump 120 isfluidly connected with the first air chamber 114A and the second airchamber 114B via a first tube 148A and a second tube 148B, respectively.The first and second control valves 145A and 145B can be controlled byswitching mechanism 138, and are operable to regulate the flow of fluidbetween the pump 120 and first and second air chambers 114A and 114B,respectively.

In some implementations, the pump 120 and the control box 124 can beprovided and packaged as a single unit. In some alternativeimplementations, the pump 120 and the control box 124 can be provided asphysically separate units. In some implementations, the control box 124,the pump 120, or both are integrated within or otherwise containedwithin a bed frame or bed support structure that supports the bed 112.In some implementations, the control box 124, the pump 120, or both arelocated outside of a bed frame or bed support structure (as shown in theexample in FIG. 1).

The example air bed system 100 depicted in FIG. 2 includes the two airchambers 114A and 114B and the single pump 120. However, otherimplementations can include an air bed system having two or more airchambers and one or more pumps incorporated into the air bed system tocontrol the air chambers. For example, a separate pump can be associatedwith each air chamber of the air bed system or a pump can be associatedwith multiple chambers of the air bed system. Separate pumps can alloweach air chamber to be inflated or deflated independently andsimultaneously. Furthermore, additional pressure transducers can also beincorporated into the air bed system such that, for example, a separatepressure transducer can be associated with each air chamber.

In use, the processor 136 can, for example, send a decrease pressurecommand to one of air chambers 114A or 114B, and the switching mechanism138 can be used to convert the low voltage command signals sent by theprocessor 136 to higher operating voltages sufficient to operate therelief valve 144 of the pump 120 and open the control valve 145A or145B. Opening the relief valve 144 can allow air to escape from the airchamber 114A or 114B through the respective air tube 148A or 148B.During deflation, the pressure transducer 146 can send pressure readingsto the processor 136 via the A/D converter 140. The A/D converter 140can receive analog information from pressure transducer 146 and canconvert the analog information to digital information useable by theprocessor 136. The processor 136 can send the digital signal to theremote control 122 to update the display 126 in order to convey thepressure information to the user.

As another example, the processor 136 can send an increase pressurecommand. The pump motor 142 can be energized in response to the increasepressure command and send air to the designated one of the air chambers114A or 114B through the air tube 148A or 148B via electronicallyoperating the corresponding valve 145A or 145B. While air is beingdelivered to the designated air chamber 114A or 114B in order toincrease the firmness of the chamber, the pressure transducer 146 cansense pressure within the pump manifold 143. Again, the pressuretransducer 146 can send pressure readings to the processor 136 via theA/D converter 140. The processor 136 can use the information receivedfrom the A/D converter 140 to determine the difference between theactual pressure in air chamber 114A or 114B and the desired pressure.The processor 136 can send the digital signal to the remote control 122to update display 126 in order to convey the pressure information to theuser.

Generally speaking, during an inflation or deflation process, thepressure sensed within the pump manifold 143 can provide anapproximation of the pressure within the respective air chamber that isin fluid communication with the pump manifold 143. An example method ofobtaining a pump manifold pressure reading that is substantiallyequivalent to the actual pressure within an air chamber includes turningoff pump 120, allowing the pressure within the air chamber 114A or 114Band the pump manifold 143 to equalize, and then sensing the pressurewithin the pump manifold 143 with the pressure transducer 146. Thus,providing a sufficient amount of time to allow the pressures within thepump manifold 143 and chamber 114A or 114B to equalize can result inpressure readings that are accurate approximations of the actualpressure within air chamber 114A or 114B. In some implementations, thepressure of the air chambers 114A and/or 114B can be continuouslymonitored using multiple pressure sensors (not shown).

In some implementations, information collected by the pressuretransducer 146 can be analyzed to determine various states of a personlying on the bed 112. For example, the processor 136 can use informationcollected by the pressure transducer 146 to determine a heart rate or arespiration rate for a person lying in the bed 112. For example, a usercan be lying on a side of the bed 112 that includes the chamber 114A.The pressure transducer 146 can monitor fluctuations in pressure of thechamber 114A and this information can be used to determine the user'sheart rate and/or respiration rate. As another example, additionalprocessing can be performed using the collected data to determine asleep state of the person (e.g., awake, light sleep, deep sleep). Forexample, the processor 136 can determine when a person falls asleep and,while asleep, the various sleep states of the person.

Additional information associated with a user of the air bed system 100that can be determined using information collected by the pressuretransducer 146 includes motion of the user, presence of the user on asurface of the bed 112, weight of the user, heart arrhythmia of theuser, and apnea. Taking user presence detection for example, thepressure transducer 146 can be used to detect the user's presence on thebed 112, e.g., via a gross pressure change determination and/or via oneor more of a respiration rate signal, heart rate signal, and/or otherbiometric signals. For example, a simple pressure detection process canidentify an increase in pressure as an indication that the user ispresent on the bed 112. As another example, the processor 136 candetermine that the user is present on the bed 112 if the detectedpressure increases above a specified threshold (so as to indicate that aperson or other object above a certain weight is positioned on the bed112). As yet another example, the processor 136 can identify an increasein pressure in combination with detected slight, rhythmic fluctuationsin pressure as corresponding to the user being present on the bed 112.The presence of rhythmic fluctuations can be identified as being causedby respiration or heart rhythm (or both) of the user. The detection ofrespiration or a heartbeat can distinguish between the user beingpresent on the bed and another object (e.g., a suit case) being placedupon the bed.

In some implementations, fluctuations in pressure can be measured at thepump 120. For example, one or more pressure sensors can be locatedwithin one or more internal cavities of the pump 120 to detectfluctuations in pressure within the pump 120. The fluctuations inpressure detected at the pump 120 can indicate fluctuations in pressurein one or both of the chambers 114A and 114B. One or more sensorslocated at the pump 120 can be in fluid communication with the one orboth of the chambers 114A and 114B, and the sensors can be operative todetermine pressure within the chambers 114A and 114B. The control box124 can be configured to determine at least one vital sign (e.g., heartrate, respiratory rate) based on the pressure within the chamber 114A orthe chamber 114B.

In some implementations, the control box 124 can analyze a pressuresignal detected by one or more pressure sensors to determine a heartrate, respiration rate, and/or other vital signs of a user lying orsitting on the chamber 114A or the chamber 114B. More specifically, whena user lies on the bed 112 positioned over the chamber 114A, each of theuser's heart beats, breaths, and other movements can create a force onthe bed 112 that is transmitted to the chamber 114A. As a result of theforce input to the chamber 114A from the user's movement, a wave canpropagate through the chamber 114A and into the pump 120. A pressuresensor located at the pump 120 can detect the wave, and thus thepressure signal output by the sensor can indicate a heart rate,respiratory rate, or other information regarding the user.

With regard to sleep state, air bed system 100 can determine a user'ssleep state by using various biometric signals such as heart rate,respiration, and/or movement of the user. While the user is sleeping,the processor 136 can receive one or more of the user's biometricsignals (e.g., heart rate, respiration, and motion) and determine theuser's present sleep state based on the received biometric signals. Insome implementations, signals indicating fluctuations in pressure in oneor both of the chambers 114A and 114B can be amplified and/or filteredto allow for more precise detection of heart rate and respiratory rate.

The control box 124 can perform a pattern recognition algorithm or othercalculation based on the amplified and filtered pressure signal todetermine the user's heart rate and respiratory rate. For example, thealgorithm or calculation can be based on assumptions that a heart rateportion of the signal has a frequency in the range of 0.5-4.0 Hz andthat a respiration rate portion of the signal a has a frequency in therange of less than 1 Hz. The control box 124 can also be configured todetermine other characteristics of a user based on the received pressuresignal, such as blood pressure, tossing and turning movements, rollingmovements, limb movements, weight, the presence or lack of presence of auser, and/or the identity of the user. Techniques for monitoring auser's sleep using heart rate information, respiration rate information,and other user information are disclosed in U.S. Patent ApplicationPublication No. 20100170043 to Steven J. Young et al., titled “APPARATUSFOR MONITORING VITAL SIGNS,” the entire contents of which isincorporated herein by reference.

For example, the pressure transducer 146 can be used to monitor the airpressure in the chambers 114A and 114B of the bed 112. If the user onthe bed 112 is not moving, the air pressure changes in the air chamber114A or 114B can be relatively minimal, and can be attributable torespiration and/or heartbeat. When the user on the bed 112 is moving,however, the air pressure in the mattress can fluctuate by a much largeramount. Thus, the pressure signals generated by the pressure transducer146 and received by the processor 136 can be filtered and indicated ascorresponding to motion, heartbeat, or respiration.

In some implementations, rather than performing the data analysis in thecontrol box 124 with the processor 136, a digital signal processor (DSP)can be provided to analyze the data collected by the pressure transducer146. Alternatively, the data collected by the pressure transducer 146could be sent to a cloud-based computing system for remote analysis.

In some implementations, the example air bed system 100 further includesa temperature controller configured to increase, decrease, or maintainthe temperature of a bed, for example for the comfort of the user. Forexample, a pad can be placed on top of or be part of the bed 112, or canbe placed on top of or be part of one or both of the chambers 114A and114B. Air can be pushed through the pad and vented to cool off a user ofthe bed. Conversely, the pad can include a heating element that can beused to keep the user warm. In some implementations, the temperaturecontroller can receive temperature readings from the pad. In someimplementations, separate pads are used for the different sides of thebed 112 (e.g., corresponding to the locations of the chambers 114A and114B) to provide for differing temperature control for the differentsides of the bed.

In some implementations, the user of the air bed system 100 can use aninput device, such as the remote control 122, to input a desiredtemperature for the surface of the bed 112 (or for a portion of thesurface of the bed 112). The desired temperature can be encapsulated ina command data structure that includes the desired temperature as wellas identifies the temperature controller as the desired component to becontrolled. The command data structure can then be transmitted viaBluetooth or another suitable communication protocol to the processor136. In various examples, the command data structure is encrypted beforebeing transmitted. The temperature controller can then configure itselements to increase or decrease the temperature of the pad depending onthe temperature input into remote control 122 by the user.

In some implementations, data can be transmitted from a component backto the processor 136 or to one or more display devices, such as thedisplay 126. For example, the current temperature as determined by asensor element of temperature controller, the pressure of the bed, thecurrent position of the foundation or other information can betransmitted to control box 124. The control box 124 can then transmitthe received information to remote control 122 where it can be displayedto the user (e.g., on the display 126).

In some implementations, the example air bed system 100 further includesan adjustable foundation and an articulation controller configured toadjust the position of a bed (e.g., the bed 112) by adjusting theadjustable foundation that supports the bed. For example, thearticulation controller can adjust the bed 112 from a flat position to aposition in which a head portion of a mattress of the bed is inclinedupward (e.g., to facilitate a user sitting up in bed and/or watchingtelevision). In some implementations, the bed 112 includes multipleseparately articulable sections. For example, portions of the bedcorresponding to the locations of the chambers 114A and 114B can bearticulated independently from each other, to allow one personpositioned on the bed 112 surface to rest in a first position (e.g., aflat position) while a second person rests in a second position (e.g.,an reclining position with the head raised at an angle from the waist).In some implementations, separate positions can be set for two differentbeds (e.g., two twin beds placed next to each other). The foundation ofthe bed 112 can include more than one zone that can be independentlyadjusted. The articulation controller can also be configured to providedifferent levels of massage to one or more users on the bed 112. FIG. 3shows an example environment 300 including a bed 302 in communicationwith devices located in and around a home. In the example shown, the bed302 includes pump 304 for controlling air pressure within two airchambers 306 a and 306 b (as described above with respect to the airchambers 114A-114B). The pump 304 additionally includes circuitry forcontrolling inflation and deflation functionality performed by the pump304. The circuitry is further programmed to detect fluctuations in airpressure of the air chambers 306 a-b and used the detected fluctuationsin air pressure to identify bed presence of a user 308, sleep state ofthe user 308, movement of the user 308, and biometric signals of theuser 308 such as heart rate and respiration rate. In the example shown,the pump 304 is located within a support structure of the bed 302 andthe control circuitry 334 for controlling the pump 304 is integratedwith the pump 304. In some implementations, the control circuitry 334 isphysically separate from the pump 304 and is in wireless or wiredcommunication with the pump 304. In some implementations, the pump 304and/or control circuitry 334 are located outside of the bed 302. In someimplementations, various control functions can be performed by systemslocated in different physical locations. For example, circuitry forcontrolling actions of the pump 304 can be located within a pump casingof the pump 304 while control circuitry 334 for performing otherfunctions associated with the bed 302 can be located in another portionof the bed 302, or external to the bed 302. As another example, controlcircuitry 334 located within the pump 304 can communicate with controlcircuitry 334 at a remote location through a LAN or WAN (e.g., theinternet). As yet another example, the control circuitry 334 can beincluded in the control box 124 of FIGS. 1 and 2.

In some implementations, one or more devices other than, or in additionto, the pump 304 and control circuitry 334 can be utilized to identifyuser bed presence, sleep state, movement, and biometric signals. Forexample, the bed 302 can include a second pump in addition to the pump304, with each of the two pumps connected to a respective one of the airchambers 306 a-b. For example, the pump 304 can be in fluidcommunication with the air chamber 306 b to control inflation anddeflation of the air chamber 306 b as well as detect user signals for auser located over the air chamber 306 b such as bed presence, sleepstate, movement, and biometric signals while the second pump is in fluidcommunication with the air chamber 306 a to control inflation anddeflation of the air chamber 306 a as well as detect user signals for auser located over the air chamber 306 a.

As another example, the bed 302 can include one or more pressuresensitive pads or surface portions that are operable to detect movement,including user presence, user motion, respiration, and heart rate. Forexample, a first pressure sensitive pad can be incorporated into asurface of the bed 302 over a left portion of the bed 302, where a firstuser would normally be located during sleep, and a second pressuresensitive pad can be incorporated into the surface of the bed 302 over aright portion of the bed 302, where a second user would normally belocated during sleep. The movement detected by the one or more pressuresensitive pads or surface portions can be used by control circuitry 334to identify user sleep state, bed presence, or biometric signals.

In some implementations, information detected by the bed (e.g., motioninformation) is processed by control circuitry 334 (e.g., controlcircuitry 334 integrated with the pump 304) and provided to one or moreuser devices such as a user device 310 for presentation to the user 308or to other users. In the example depicted in FIG. 3, the user device310 is a tablet device; however, in some implementations, the userdevice 310 can be a personal computer, a smart phone, a smart television(e.g., a television 312), or other user device capable of wired orwireless communication with the control circuitry 334. The user device310 can be in communication with control circuitry 334 of the bed 302through a network or through direct point-to-point communication. Forexample, the control circuitry 334 can be connected to a LAN (e.g.,through a Wi-Fi router) and communicate with the user device 310 throughthe LAN. As another example, the control circuitry 334 and the userdevice 310 can both connect to the Internet and communicate through theInternet. For example, the control circuitry 334 can connect to theInternet through a WiFi router and the user device 310 can connect tothe Internet through communication with a cellular communication system.As another example, the control circuitry 334 can communicate directlywith the user device 310 through a wireless communication protocol suchas Bluetooth. As yet another example, the control circuitry 334 cancommunicate with the user device 310 through a wireless communicationprotocol such as ZigBee, Z-Wave, infrared, or another wirelesscommunication protocol suitable for the application. As another example,the control circuitry 334 can communicate with the user device 310through a wired connection such as, for example, a USB connector,serial/RS232 or another wired connection suitable for the application.

The user device 310 can display a variety of information and statisticsrelated to sleep, or user 308's interaction with the bed 302. Forexample, a user interface displayed by the user device 310 can presentinformation including amount of sleep for the user 308 over a period oftime (e.g., a single evening, a week, a month, etc.) amount of deepsleep, ratio of deep sleep to restless sleep, time lapse between theuser 308 getting into bed and the user 308 falling asleep, total amountof time spent in the bed 302 for a given period of time, heart rate forthe user 308 over a period of time, respiration rate for the user 308over a period of time, or other information related to user interactionwith the bed 302 by the user 308 or one or more other users of the bed302. In some implementations, information for multiple users can bepresented on the user device 310, for example information for a firstuser positioned over the air chamber 306 a can be presented along withinformation for a second user positioned over the air chamber 306 b. Insome implementations, the information presented on the user device 310can vary according to the age of the user 308. For example, theinformation presented on the user device 310 can evolve with the age ofthe user 308 such that different information is presented on the userdevice 310 as the user 308 ages as a child or an adult.

The user device 310 can also be used as an interface for the controlcircuitry 334 of the bed 302 to allow the user 308 to enter information.The information entered by the user 308 can be used by the controlcircuitry 334 to provide better information to the user or to variouscontrol signals for controlling functions of the bed 302 or otherdevices. For example, the user can enter information such as weight,height, and age and the control circuitry 334 can use this informationto provide the user 308 with a comparison of the user's tracked sleepinformation to sleep information of other people having similar weights,heights, and/or ages as the user 308. As another example, the user 308can use the user device 310 as an interface for controlling air pressureof the air chambers 306 a and 306 b, for controlling various recline orincline positions of the bed 302, for controlling temperature of one ormore surface temperature control devices of the bed 302, or for allowingthe control circuitry 334 to generate control signals for other devices(as described in greater detail below).

In some implementations, control circuitry 334 of the bed 302 (e.g.,control circuitry 334 integrated into the pump 304) can communicate withother devices or systems in addition to or instead of the user device310. For example, the control circuitry 334 can communicate with thetelevision 312, a lighting system 314, a thermostat 316, a securitysystem 318, or other house hold devices such as an oven 322, a coffeemaker 324, a lamp 326, and a nightlight 328. Other examples of devicesand/or systems that the control circuitry 334 can communicate withinclude a system for controlling window blinds 330, one or more devicesfor detecting or controlling the states of one or more doors 332 (suchas detecting if a door is open, detecting if a door is locked, orautomatically locking a door), and a system for controlling a garagedoor 320 (e.g., control circuitry 334 integrated with a garage dooropener for identifying an open or closed state of the garage door 320and for causing the garage door opener to open or close the garage door320). Communications between the control circuitry 334 of the bed 302and other devices can occur through a network (e.g., a LAN or theInternet) or as point-to-point communication (e.g., using Bluetooth,radio communication, or a wired connection). In some implementations,control circuitry 334 of different beds 302 can communicate withdifferent sets of devices. For example, a kid bed may not communicatewith and/or control the same devices as an adult bed. In someembodiments, the bed 302 can evolve with the age of the user such thatthe control circuitry 334 of the bed 302 communicates with differentdevices as a function of age of the user.

The control circuitry 334 can receive information and inputs from otherdevices/systems and use the received information and inputs to controlactions of the bed 302 or other devices. For example, the controlcircuitry 334 can receive information from the thermostat 316 indicatinga current environmental temperature for a house or room in which the bed302 is located. The control circuitry 334 can use the receivedinformation (along with other information) to determine if a temperatureof all or a portion of the surface of the bed 302 should be raised orlowered. The control circuitry 334 can then cause a heating or coolingmechanism of the bed 302 to raise or lower the temperature of thesurface of the bed 302. For example, the user 308 can indicate a desiredsleeping temperature of 74 degrees while a second user of the bed 302indicates a desired sleeping temperature of 72 degrees. The thermostat316 can indicate to the control circuitry 334 that the currenttemperature of the bedroom is 72 degrees. The control circuitry 334 canidentify that the user 308 has indicated a desired sleeping temperatureof 74 degrees, and send control signals to a heating pad located on theuser 308's side of the bed to raise the temperature of the portion ofthe surface of the bed 302 where the user 308 is located to raise thetemperature of the user 308's sleeping surface to the desiredtemperature.

The control circuitry 334 can also generate control signals controllingother devices and propagate the control signals to the other devices. Insome implementations, the control signals are generated based oninformation collected by the control circuitry 334, includinginformation related to user interaction with the bed 302 by the user 308and/or one or more other users. In some implementations, informationcollected from one or more other devices other than the bed 302 are usedwhen generating the control signals. For example, information relatingto environmental occurrences (e.g., environmental temperature,environmental noise level, and environmental light level), time of day,time of year, day of the week, or other information can be used whengenerating control signals for various devices in communication with thecontrol circuitry 334 of the bed 302. For example, information on thetime of day can be combined with information relating to movement andbed presence of the user 308 to generate control signals for thelighting system 314. In some implementations, rather than or in additionto providing control signals for one or more other devices, the controlcircuitry 334 can provide collected information (e.g., informationrelated to user movement, bed presence, sleep state, or biometricsignals for the user 308) to one or more other devices to allow the oneor more other devices to utilize the collected information whengenerating control signals. For example, control circuitry 334 of thebed 302 can provide information relating to user interactions with thebed 302 by the user 308 to a central controller (not shown) that can usethe provided information to generate control signals for variousdevices, including the bed 302.

Still referring to FIG. 3, the control circuitry 334 of the bed 302 cangenerate control signals for controlling actions of other devices, andtransmit the control signals to the other devices in response toinformation collected by the control circuitry 334, including bedpresence of the user 308, sleep state of the user 308, and otherfactors. For example, control circuitry 334 integrated with the pump 304can detect a feature of a mattress of the bed 302, such as an increasein pressure in the air chamber 306 b, and use this detected increase inair pressure to determine that the user 308 is present on the bed 302.In some implementations, the control circuitry 334 can identify a heartrate or respiratory rate for the user 308 to identify that the increasein pressure is due to a person sitting, laying, or otherwise resting onthe bed 302 rather than an inanimate object (such as a suitcase) havingbeen placed on the bed 302. In some implementations, the informationindicating user bed presence is combined with other information toidentify a current or future likely state for the user 308. For example,a detected user bed presence at 11:00 am can indicate that the user issitting on the bed (e.g., to tie her shoes, or to read a book) and doesnot intend to go to sleep, while a detected user bed presence at 10:00pm can indicate that the user 308 is in bed for the evening and isintending to fall asleep soon. As another example, if the controlcircuitry 334 detects that the user 308 has left the bed 302 at 6:30 am(e.g., indicating that the user 308 has woken up for the day), and thenlater detects user bed presence of the user 308 at 7:30 am, the controlcircuitry 334 can use this information that the newly detected user bedpresence is likely temporary (e.g., while the user 308 ties her shoesbefore heading to work) rather than an indication that the user 308 isintending to stay on the bed 302 for an extended period.

In some implementations, the control circuitry 334 is able to usecollected information (including information related to user interactionwith the bed 302 by the user 308, as well as environmental information,time information, and input received from the user) to identify usepatterns for the user 308. For example, the control circuitry 334 canuse information indicating bed presence and sleep states for the user308 collected over a period of time to identify a sleep pattern for theuser. For example, the control circuitry 334 can identify that the user308 generally goes to bed between 9:30 pm and 10:00 pm, generally fallsasleep between 10:00 pm and 11:00 pm, and generally wakes up between6:30 am and 6:45 am based on information indicating user presence andbiometrics for the user 308 collected over a week. The control circuitry334 can use identified patterns for a user to better process andidentify user interactions with the bed 302 by the user 308.

For example, given the above example user bed presence, sleep, and wakepatterns for the user 308, if the user 308 is detected as being on thebed at 3:00 pm, the control circuitry 334 can determine that the user'spresence on the bed is only temporary, and use this determination togenerate different control signals than would be generated if thecontrol circuitry 334 determined that the user 308 was in bed for theevening. As another example, if the control circuitry 334 detects thatthe user 308 has gotten out of bed at 3:00 am, the control circuitry 334can use identified patterns for the user 308 to determine that the userhas only gotten up temporarily (for example, to use the rest room, orget a glass of water) and is not up for the day. By contrast, if thecontrol circuitry 334 identifies that the user 308 has gotten out of thebed 302 at 6:40 am, the control circuitry 334 can determine that theuser is up for the day and generate a different set of control signalsthan those that would be generated if it were determined that the user308 were only getting out of bed temporarily (as would be the case whenthe user 308 gets out of the bed 302 at 3:00 am). For other users 308,getting out of the bed 302 at 3:00 am can be the normal wake-up time,which the control circuitry 334 can learn and respond to accordingly.

As described above, the control circuitry 334 for the bed 302 cangenerate control signals for control functions of various other devices.The control signals can be generated, at least in part, based ondetected interactions by the user 308 with the bed 302, as well as otherinformation including time, date, temperature, etc. For example, thecontrol circuitry 334 can communicate with the television 312, receiveinformation from the television 312, and generate control signals forcontrolling functions of the television 312. For example, the controlcircuitry 334 can receive an indication from the television 312 that thetelevision 312 is currently on. If the television 312 is located in adifferent room from the bed 302, the control circuitry 334 can generatea control signal to turn the television 312 off upon making adetermination that the user 308 has gone to bed for the evening. Forexample, if bed presence of the user 308 on the bed 302 is detectedduring a particular time range (e.g., between 8:00 pm and 7:00 am) andpersists for longer than a threshold period of time (e.g., 10 minutes)the control circuitry 334 can use this information to determine that theuser 308 is in bed for the evening. If the television 312 is on (asindicated by communications received by the control circuitry 334 of thebed 302 from the television 312) the control circuitry 334 can generatea control signal to turn the television 312 off. The control signals canthen be transmitted to the television (e.g., through a directedcommunication link between the television 312 and the control circuitry334 or through a network). As another example, rather than turning offthe television 312 in response to detection of user bed presence, thecontrol circuitry 334 can generate a control signal that causes thevolume of the television 312 to be lowered by a pre-specified amount.

As another example, upon detecting that the user 308 has left the bed302 during a specified time range (e.g., between 6:00 am and 8:00 am)the control circuitry 334 can generate control signals to cause thetelevision 312 to turn on and tune to a pre-specified channel (e.g., theuser 308 has indicated a preference for watching the morning news upongetting out of bed in the morning). The control circuitry 334 cangenerate the control signal and transmit the signal to the television312 to cause the television 312 to turn on and tune to the desiredstation (which could be stored at the control circuitry 334, thetelevision 312, or another location). As another example, upon detectingthat the user 308 has gotten up for the day, the control circuitry 334can generate and transmit control signals to cause the television 312 toturn on and begin playing a previously recorded program from a digitalvideo recorder (DVR) in communication with the television 312.

As another example, if the television 312 is in the same room as the bed302, the control circuitry 334 does not cause the television 312 to turnoff in response to detection of user bed presence. Rather, the controlcircuitry 334 can generate and transmit control signals to cause thetelevision 312 to turn off in response to determining that the user 308is asleep. For example, the control circuitry 334 can monitor biometricsignals of the user 308 (e.g., motion, heart rate, respiration rate) todetermine that the user 308 has fallen asleep. Upon detecting that theuser 308 is sleeping, the control circuitry 334 generates and transmitsa control signal to turn the television 312 off. As another example, thecontrol circuitry 334 can generate the control signal to turn off thetelevision 312 after a threshold period of time after the user 308 hasfallen asleep (e.g., 10 minutes after the user has fallen asleep). Asanother example, the control circuitry 334 generates control signals tolower the volume of the television 312 after determining that the user308 is asleep. As yet another example, the control circuitry 334generates and transmits a control signal to cause the television togradually lower in volume over a period of time and then turn off inresponse to determining that the user 308 is asleep.

In some implementations, the control circuitry 334 can similarlyinteract with other media devices, such as computers, tablets, smartphones, stereo systems, etc. For example, upon detecting that the user308 is asleep, the control circuitry 334 can generate and transmit acontrol signal to the user device 310 to cause the user device 310 toturn off, or turn down the volume on a video or audio file being playedby the user device 310.

The control circuitry 334 can additionally communicate with the lightingsystem 314, receive information from the lighting system 314, andgenerate control signals for controlling functions of the lightingsystem 314. For example, upon detecting user bed presence on the bed 302during a certain time frame (e.g., between 8:00 pm and 7:00 am) thatlasts for longer than a threshold period of time (e.g., 10 minutes) thecontrol circuitry 334 of the bed 302 can determine that the user 308 isin bed for the evening. In response to this determination, the controlcircuitry 334 can generate control signals to cause lights in one ormore rooms other than the room in which the bed 302 is located to switchoff. The control signals can then be transmitted to the lighting system314 and executed by the lighting system 314 to cause the lights in theindicated rooms to shut off. For example, the control circuitry 334 cangenerate and transmit control signals to turn off lights in all commonrooms, but not in other bedrooms. As another example, the controlsignals generated by the control circuitry 334 can indicate that lightsin all rooms other than the room in which the bed 302 is located are tobe turned off, while one or more lights located outside of the housecontaining the bed 302 are to be turned on, in response to determiningthat the user 308 is in bed for the evening. Additionally, the controlcircuitry 334 can generate and transmit control signals to cause thenightlight 328 to turn on in response to determining user 308 bedpresence or whether the user 308 is asleep. As another example, thecontrol circuitry 334 can generate first control signals for turning offa first set of lights (e.g., lights in common rooms) in response todetecting user bed presence, and second control signals for turning offa second set of lights (e.g., lights in the room in which the bed 302 islocated) in response to detecting that the user 308 is asleep.

In some implementations, in response to determining that the user 308 isin bed for the evening, the control circuitry 334 of the bed 302 cangenerate control signals to cause the lighting system 314 to implement asunset lighting scheme in the room in which the bed 302 is located. Asunset lighting scheme can include, for example, dimming the lights(either gradually over time, or all at once) in combination withchanging the color of the light in the bedroom environment, such asadding an amber hue to the lighting in the bedroom. The sunset lightingscheme can help to put the user 308 to sleep when the control circuitry334 has determined that the user 308 is in bed for the evening.

The control circuitry 334 can also be configured to implement a sunriselighting scheme when the user 308 wakes up in the morning. The controlcircuitry 334 can determine that the user 308 is awake for the day, forexample, by detecting that the user 308 has gotten off of the bed 302(i.e., is no longer present on the bed 302) during a specified timeframe (e.g., between 6:00 am and 8:00 am). As another example, thecontrol circuitry 334 can monitor movement, heart rate, respiratoryrate, or other biometric signals of the user 308 to determine that theuser 308 is awake even though the user 308 has not gotten out of bed. Ifthe control circuitry 334 detects that the user is awake during aspecified time frame, the control circuitry 334 can determine that theuser 308 is awake for the day. The specified time frame can be, forexample, based on previously recorded user bed presence informationcollected over a period of time (e.g., two weeks) that indicates thatthe user 308 usually wakes up for the day between 6:30 am and 7:30 am.In response to the control circuitry 334 determining that the user 308is awake, the control circuitry 334 can generate control signals tocause the lighting system 314 to implement the sunrise lighting schemein the bedroom in which the bed 302 is located. The sunrise lightingscheme can include, for example, turning on lights (e.g., the lamp 326,or other lights in the bedroom). The sunrise lighting scheme can furtherinclude gradually increasing the level of light in the room where thebed 302 is located (or in one or more other rooms). The sunrise lightingscheme can also include only turning on lights of specified colors. Forexample, the sunrise lighting scheme can include lighting the bedroomwith blue light to gently assist the user 308 in waking up and becomingactive.

In some implementations, the control circuitry 334 can generatedifferent control signals for controlling actions of one or morecomponents, such as the lighting system 314, depending on a time of daythat user interactions with the bed 302 are detected. For example, thecontrol circuitry 334 can use historical user interaction informationfor interactions between the user 308 and the bed 302 to determine thatthe user 308 usually falls asleep between 10:00 pm and 11:00 pm andusually wakes up between 6:30 am and 7:30 am on weekdays. The controlcircuitry 334 can use this information to generate a first set ofcontrol signals for controlling the lighting system 314 if the user 308is detected as getting out of bed at 3:00 am and to generate a secondset of control signals for controlling the lighting system 314 if theuser 308 is detected as getting out of bed after 6:30 am. For example,if the user 308 gets out of bed prior to 6:30 am, the control circuitry334 can turn on lights that guide the user 308's route to a restroom. Asanother example, if the user 308 gets out of bed prior to 6:30 am, thecontrol circuitry 334 can turn on lights that guide the user 308's routeto the kitchen (which can include, for example, turning on thenightlight 328, turning on under bed lighting, or turning on the lamp326).

As another example, if the user 308 gets out of bed after 6:30 am, thecontrol circuitry 334 can generate control signals to cause the lightingsystem 314 to initiate a sunrise lighting scheme, or to turn on one ormore lights in the bedroom and/or other rooms. In some implementations,if the user 308 is detected as getting out of bed prior to a specifiedmorning rise time for the user 308, the control circuitry 334 causes thelighting system 314 to turn on lights that are dimmer than lights thatare turned on by the lighting system 314 if the user 308 is detected asgetting out of bed after the specified morning rise time. Causing thelighting system 314 to only turn on dim lights when the user 308 getsout of bed during the night (i.e., prior to normal rise time for theuser 308) can prevent other occupants of the house from being woken bythe lights while still allowing the user 308 to see in order to reachthe restroom, kitchen, or another destination within the house.

The historical user interaction information for interactions between theuser 308 and the bed 302 can be used to identify user sleep and awaketime frames. For example, user bed presence times and sleep times can bedetermined for a set period of time (e.g., two weeks, a month, etc.).The control circuitry 334 can then identify a typical time range or timeframe in which the user 308 goes to bed, a typical time frame for whenthe user 308 falls asleep, and a typical time frame for when the user308 wakes up (and in some cases, different time frames for when the user308 wakes up and when the user 308 actually gets out of bed). In someimplementations, buffer time can be added to these time frames. Forexample, if the user is identified as typically going to bed between10:00 pm and 10:30 pm, a buffer of a half hour in each direction can beadded to the time frame such that any detection of the user getting ontothe bed between 9:30 pm and 11:00 pm is interpreted as the user 308going to bed for the evening. As another example, detection of bedpresence of the user 308 starting from a half hour before the earliesttypical time that the user 308 goes to bed extending until the typicalwake up time (e.g., 6:30 am) for the user can be interpreted as the usergoing to bed for the evening. For example, if the user typically goes tobed between 10:00 pm and 10:30 pm, if the user's bed presence is sensedat 12:30 am one night, that can be interpreted as the user getting intobed for the evening even though this is outside of the user's typicaltime frame for going to bed because it has occurred prior to the user'snormal wake up time. In some implementations, different time frames areidentified for different times of the year (e.g., earlier bed timeduring winter vs. summer) or at different times of the week (e.g., userwakes up earlier on weekdays than on weekends).

The control circuitry 334 can distinguish between the user 308 going tobed for an extended period (such as for the night) as opposed to beingpresent on the bed 302 for a shorter period (such as for a nap) bysensing duration of presence of the user 308. In some examples, thecontrol circuitry 334 can distinguish between the user 308 going to bedfor an extended period (such as for the night) as opposed to going tobed for a shorter period (such as for a nap) by sensing duration ofsleep of the user 308. For example, the control circuitry 334 can set atime threshold whereby if the user 308 is sensed on the bed 302 forlonger than the threshold, the user 308 is considered to have gone tobed for the night. In some examples, the threshold can be about 2 hours,whereby if the user 308 is sensed on the bed 302 for greater than 2hours, the control circuitry 334 registers that as an extended sleepevent. In other examples, the threshold can be greater than or less thantwo hours.

The control circuitry 334 can detect repeated extended sleep events todetermine a typical bed time range of the user 308 automatically,without requiring the user 308 to enter a bed time range. This can allowthe control circuitry 334 to accurately estimate when the user 308 islikely to go to bed for an extended sleep event, regardless of whetherthe user 308 typically goes to bed using a traditional sleep schedule ora non-traditional sleep schedule. The control circuitry 334 can then useknowledge of the bed time range of the user 308 to control one or morecomponents (including components of the bed 302 and/or non-bedperipherals) differently based on sensing bed presence during the bedtime range or outside of the bed time range.

In some examples, the control circuitry 334 can automatically determinethe bed time range of the user 308 without requiring user inputs. Insome examples, the control circuitry 334 can determine the bed timerange of the user 308 automatically and in combination with user inputs.In some examples, the control circuitry 334 can set the bed time rangedirectly according to user inputs. In some examples, the controlcircuitry 334 can associate different bed times with different days ofthe week. In each of these examples, the control circuitry 334 cancontrol one or more components (such as the lighting system 314, thethermostat 316, the security system 318, the oven 322, the coffee maker324, the lamp 326, and the nightlight 328), as a function of sensed bedpresence and the bed time range.

The control circuitry 334 can additionally communicate with thethermostat 316, receive information from the thermostat 316, andgenerate control signals for controlling functions of the thermostat316. For example, the user 308 can indicate user preferences fordifferent temperatures at different times, depending on the sleep stateor bed presence of the user 308. For example, the user 308 may prefer anenvironmental temperature of 72 degrees when out of bed, 70 degrees whenin bed but awake, and 68 degrees when sleeping. The control circuitry334 of the bed 302 can detect bed presence of the user 308 in theevening and determine that the user 308 is in bed for the night. Inresponse to this determination, the control circuitry 334 can generatecontrol signals to cause the thermostat to change the temperature to 70degrees. The control circuitry 334 can then transmit the control signalsto the thermostat 316. Upon detecting that the user 308 is in bed duringthe bed time range or asleep, the control circuitry 334 can generate andtransmit control signals to cause the thermostat 316 to change thetemperature to 68. The next morning, upon determining that the user isawake for the day (e.g., the user 308 gets out of bed after 6:30 am) thecontrol circuitry 334 can generate and transmit control circuitry 334 tocause the thermostat to change the temperature to 72 degrees.

In some implementations, the control circuitry 334 can similarlygenerate control signals to cause one or more heating or coolingelements on the surface of the bed 302 to change temperature at varioustimes, either in response to user interaction with the bed 302 or atvarious pre-programmed times. For example, the control circuitry 334 canactivate a heating element to raise the temperature of one side of thesurface of the bed 302 to 73 degrees when it is detected that the user308 has fallen asleep. As another example, upon determining that theuser 308 is up for the day, the control circuitry 334 can turn off aheating or cooling element. As yet another example, the user 308 canpre-program various times at which the temperature at the surface of thebed should be raised or lowered. For example, the user can program thebed 302 to raise the surface temperature to 76 degrees at 10:00 pm, andlower the surface temperature to 68 degrees at 11:30 pm.

In some implementations, in response to detecting user bed presence ofthe user 308 and/or that the user 308 is asleep, the control circuitry334 can cause the thermostat 316 to change the temperature in differentrooms to different values. For example, in response to determining thatthe user 308 is in bed for the evening, the control circuitry 334 cangenerate and transmit control signals to cause the thermostat 316 to setthe temperature in one or more bedrooms of the house to 72 degrees andset the temperature in other rooms to 67 degrees.

The control circuitry 334 can also receive temperature information fromthe thermostat 316 and use this temperature information to controlfunctions of the bed 302 or other devices. For example, as discussedabove, the control circuitry 334 can adjust temperatures of heatingelements included in the bed 302 in response to temperature informationreceived from the thermostat 316.

In some implementations, the control circuitry 334 can generate andtransmit control signals for controlling other temperature controlsystems. For example, in response to determining that the user 308 isawake for the day, the control circuitry 334 can generate and transmitcontrol signals for causing floor heating elements to activate. Forexample, the control circuitry 334 can cause a floor heating system fora master bedroom to turn on in response to determining that the user 308is awake for the day.

The control circuitry 334 can additionally communicate with the securitysystem 318, receive information from the security system 318, andgenerate control signals for controlling functions of the securitysystem 318. For example, in response to detecting that the user 308 inis bed for the evening, the control circuitry 334 can generate controlsignals to cause the security system to engage or disengage securityfunctions. The control circuitry 334 can then transmit the controlsignals to the security system 318 to cause the security system 318 toengage. As another example, the control circuitry 334 can generate andtransmit control signals to cause the security system 318 to disable inresponse to determining that the user 308 is awake for the day (e.g.,user 308 is no longer present on the bed 302 after 6:00 am). In someimplementations, the control circuitry 334 can generate and transmit afirst set of control signals to cause the security system 318 to engagea first set of security features in response to detecting user bedpresence of the user 308, and can generate and transmit a second set ofcontrol signals to cause the security system 318 to engage a second setof security features in response to detecting that the user 308 hasfallen asleep.

In some implementations, the control circuitry 334 can receive alertsfrom the security system 318 and indicate the alert to the user 308. Forexample, the control circuitry 334 can detect that the user 308 is inbed for the evening and in response, generate and transmit controlsignals to cause the security system 318 to engage or disengage. Thesecurity system can then detect a security breach (e.g., someone hasopened the door 332 without entering the security code, or someone hasopened a window when the security system 318 is engaged). The securitysystem 318 can communicate the security breach to the control circuitry334 of the bed 302. In response to receiving the communication from thesecurity system 318, the control circuitry 334 can generate controlsignals to alert the user 308 to the security breach. For example, thecontrol circuitry 334 can cause the bed 302 to vibrate. As anotherexample, the control circuitry 334 can cause portions of the bed 302 toarticulate (e.g., cause the head section to raise or lower) in order towake the user 308 and alert the user to the security breach. As anotherexample, the control circuitry 334 can generate and transmit controlsignals to cause the lamp 326 to flash on and off at regular intervalsto alert the user 308 to the security breach. As another example, thecontrol circuitry 334 can alert the user 308 of one bed 302 regarding asecurity breach in a bedroom of another bed, such as an open window in akid's bedroom. As another example, the control circuitry 334 can send analert to a garage door controller (e.g., to close and lock the door). Asanother example, the control circuitry 334 can send an alert for thesecurity to be disengaged.

The control circuitry 334 can additionally generate and transmit controlsignals for controlling the garage door 320 and receive informationindicating a state of the garage door 320 (i.e., open or closed). Forexample, in response to determining that the user 308 is in bed for theevening, the control circuitry 334 can generate and transmit a requestto a garage door opener or another device capable of sensing if thegarage door 320 is open. The control circuitry 334 can requestinformation on the current state of the garage door 320. If the controlcircuitry 334 receives a response (e.g., from the garage door opener)indicating that the garage door 320 is open, the control circuitry 334can either notify the user 308 that the garage door is open, or generatea control signal to cause the garage door opener to close the garagedoor 320. For example, the control circuitry 334 can send a message tothe user device 310 indicating that the garage door is open. As anotherexample, the control circuitry 334 can cause the bed 302 to vibrate. Asyet another example, the control circuitry 334 can generate and transmita control signal to cause the lighting system 314 to cause one or morelights in the bedroom to flash to alert the user 308 to check the userdevice 310 for an alert (in this example, an alert regarding the garagedoor 320 being open). Alternatively, or additionally, the controlcircuitry 334 can generate and transmit control signals to cause thegarage door opener to close the garage door 320 in response toidentifying that the user 308 is in bed for the evening and that thegarage door 320 is open. In some implementations, control signals canvary depend on the age of the user 308.

The control circuitry 334 can similarly send and receive communicationsfor controlling or receiving state information associated with the door332 or the oven 322. For example, upon detecting that the user 308 is inbed for the evening, the control circuitry 334 can generate and transmita request to a device or system for detecting a state of the door 332.Information returned in response to the request can indicate variousstates for the door 332 such as open, closed but unlocked, or closed andlocked. If the door 332 is open or closed but unlocked, the controlcircuitry 334 can alert the user 308 to the state of the door, such asin a manner described above with reference to the garage door 320.Alternatively, or in addition to alerting the user 308, the controlcircuitry 334 can generate and transmit control signals to cause thedoor 332 to lock, or to close and lock. If the door 332 is closed andlocked, the control circuitry 334 can determine that no further actionis needed.

Similarly, upon detecting that the user 308 is in bed for the evening,the control circuitry 334 can generate and transmit a request to theoven 322 to request a state of the oven 322 (e.g., on or off). If theoven 322 is on, the control circuitry 334 can alert the user 308 and/orgenerate and transmit control signals to cause the oven 322 to turn off.If the oven is already off, the control circuitry 334 can determine thatno further action is necessary. In some implementations, differentalerts can be generated for different events. For example, the controlcircuitry 334 can cause the lamp 326 (or one or more other lights, viathe lighting system 314) to flash in a first pattern if the securitysystem 318 has detected a breach, flash in a second pattern if garagedoor 320 is on, flash in a third pattern if the door 332 is open, flashin a fourth pattern if the oven 322 is on, and flash in a fifth patternif another bed has detected that a user of that bed has gotten up (e.g.,that a child of the user 308 has gotten out of bed in the middle of thenight as sensed by a sensor in the bed 302 of the child). Other examplesof alerts that can be processed by the control circuitry 334 of the bed302 and communicated to the user include a smoke detector detectingsmoke (and communicating this detection of smoke to the controlcircuitry 334), a carbon monoxide tester detecting carbon monoxide, aheater malfunctioning, or an alert from any other device capable ofcommunicating with the control circuitry 334 and detecting an occurrencethat should be brought to the user 308's attention.

The control circuitry 334 can also communicate with a system or devicefor controlling a state of the window blinds 330. For example, inresponse to determining that the user 308 is in bed for the evening, thecontrol circuitry 334 can generate and transmit control signals to causethe window blinds 330 to close. As another example, in response todetermining that the user 308 is up for the day (e.g., user has gottenout of bed after 6:30 am) the control circuitry 334 can generate andtransmit control signals to cause the window blinds 330 to open. Bycontrast, if the user 308 gets out of bed prior to a normal rise timefor the user 308, the control circuitry 334 can determine that the user308 is not awake for the day and does not generate control signals forcausing the window blinds 330 to open. As yet another example, thecontrol circuitry 334 can generate and transmit control signals thatcause a first set of blinds to close in response to detecting user bedpresence of the user 308 and a second set of blinds to close in responseto detecting that the user 308 is asleep.

The control circuitry 334 can generate and transmit control signals forcontrolling functions of other household devices in response todetecting user interactions with the bed 302. For example, in responseto determining that the user 308 is awake for the day, the controlcircuitry 334 can generate and transmit control signals to the coffeemaker 324 to cause the coffee maker 324 to begin brewing coffee. Asanother example, the control circuitry 334 can generate and transmitcontrol signals to the oven 322 to cause the oven to begin preheating(for users that like fresh baked bread in the morning). As anotherexample, the control circuitry 334 can use information indicating thatthe user 308 is awake for the day along with information indicating thatthe time of year is currently winter and/or that the outside temperatureis below a threshold value to generate and transmit control signals tocause a car engine block heater to turn on.

As another example, the control circuitry 334 can generate and transmitcontrol signals to cause one or more devices to enter a sleep mode inresponse to detecting user bed presence of the user 308, or in responseto detecting that the user 308 is asleep. For example, the controlcircuitry 334 can generate control signals to cause a mobile phone ofthe user 308 to switch into sleep mode. The control circuitry 334 canthen transmit the control signals to the mobile phone. Later, upondetermining that the user 308 is up for the day, the control circuitry334 can generate and transmit control signals to cause the mobile phoneto switch out of sleep mode.

In some implementations, the control circuitry 334 can communicate withone or more noise control devices. For example, upon determining thatthe user 308 is in bed for the evening, or that the user 308 is asleep,the control circuitry 334 can generate and transmit control signals tocause one or more noise cancelation devices to activate. The noisecancelation devices can, for example, be included as part of the bed 302or located in the bedroom with the bed 302. As another example, upondetermining that the user 308 is in bed for the evening or that the user308 is asleep, the control circuitry 334 can generate and transmitcontrol signals to turn the volume on, off, up, or down, for one or moresound generating devices, such as a stereo system radio, computer,tablet, etc.

Additionally, functions of the bed 302 are controlled by the controlcircuitry 334 in response to user interactions with the bed 302. Forexample, the bed 302 can include an adjustable foundation and anarticulation controller configured to adjust the position of one or moreportions of the bed 302 by adjusting the adjustable foundation thatsupports the bed. For example, the articulation controller can adjustthe bed 302 from a flat position to a position in which a head portionof a mattress of the bed 302 is inclined upward (e.g., to facilitate auser sitting up in bed and/or watching television). In someimplementations, the bed 302 includes multiple separately articulablesections. For example, portions of the bed corresponding to thelocations of the air chambers 306 a and 306 b can be articulatedindependently from each other, to allow one person positioned on the bed302 surface to rest in a first position (e.g., a flat position) while asecond person rests in a second position (e.g., a reclining positionwith the head raised at an angle from the waist). In someimplementations, separate positions can be set for two different beds(e.g., two twin beds placed next to each other). The foundation of thebed 302 can include more than one zone that can be independentlyadjusted. The articulation controller can also be configured to providedifferent levels of massage to one or more users on the bed 302 or tocause the bed to vibrate to communicate alerts to the user 308 asdescribed above.

The control circuitry 334 can adjust positions (e.g., incline anddecline positions for the user 308 and/or an additional user of the bed302) in response to user interactions with the bed 302. For example, thecontrol circuitry 334 can cause the articulation controller to adjustthe bed 302 to a first recline position for the user 308 in response tosensing user bed presence for the user 308. The control circuitry 334can cause the articulation controller to adjust the bed 302 to a secondrecline position (e.g., a less reclined, or flat position) in responseto determining that the user 308 is asleep. As another example, thecontrol circuitry 334 can receive a communication from the television312 indicating that the user 308 has turned off the television 312, andin response the control circuitry 334 can cause the articulationcontroller to adjust the position of the bed 302 to a preferred usersleeping position (e.g., due to the user turning off the television 312while the user 308 is in bed indicating that the user 308 wishes to goto sleep).

In some implementations, the control circuitry 334 can control thearticulation controller so as to wake up one user of the bed 302 withoutwaking another user of the bed 302. For example, the user 308 and asecond user of the bed 302 can each set distinct wakeup times (e.g.,6:30 am and 7:15 am respectively). When the wakeup time for the user 308is reached, the control circuitry 334 can cause the articulationcontroller to vibrate or change the position of only a side of the bedon which the user 308 is located to wake the user 308 without disturbingthe second user. When the wakeup time for the second user is reached,the control circuitry 334 can cause the articulation controller tovibrate or change the position of only the side of the bed on which thesecond user is located. Alternatively, when the second wakeup timeoccurs, the control circuitry 334 can utilize other methods (such asaudio alarms, or turning on the lights) to wake the second user sincethe user 308 is already awake and therefore will not be disturbed whenthe control circuitry 334 attempts to wake the second user.

Still referring to FIG. 3, the control circuitry 334 for the bed 302 canutilize information for interactions with the bed 302 by multiple usersto generate control signals for controlling functions of various otherdevices. For example, the control circuitry 334 can wait to generatecontrol signals for, for example, engaging the security system 318, orinstructing the lighting system 314 to turn off lights in various roomsuntil both the user 308 and a second user are detected as being presenton the bed 302. As another example, the control circuitry 334 cangenerate a first set of control signals to cause the lighting system 314to turn off a first set of lights upon detecting bed presence of theuser 308 and generate a second set of control signals for turning off asecond set of lights in response to detecting bed presence of a seconduser. As another example, the control circuitry 334 can wait until ithas been determined that both the user 308 and a second user are awakefor the day before generating control signals to open the window blinds330. As yet another example, in response to determining that the user308 has left the bed and is awake for the day, but that a second user isstill sleeping, the control circuitry 334 can generate and transmit afirst set of control signals to cause the coffee maker 324 to beginbrewing coffee, to cause the security system 318 to deactivate, to turnon the lamp 326, to turn off the nightlight 328, to cause the thermostat316 to raise the temperature in one or more rooms to 72 degrees, and toopen blinds (e.g., the window blinds 330) in rooms other than thebedroom in which the bed 302 is located. Later, in response to detectingthat the second user is no longer present on the bed (or that the seconduser is awake) the control circuitry 334 can generate and transmit asecond set of control signals to, for example, cause the lighting system314 to turn on one or more lights in the bedroom, to cause window blindsin the bedroom to open, and to turn on the television 312 to apre-specified channel.

Described here are examples of systems and components that can be usedfor data processing tasks that are, for example, associated with a bed.In some cases, multiple examples of a particular component or group ofcomponents are presented. Some of these examples are redundant and/ormutually exclusive alternatives. Connections between components areshown as examples to illustrate possible network configurations forallowing communication between components. Different formats ofconnections can be used as technically needed or desired. Theconnections generally indicate a logical connection that can be createdwith any technologically feasible format. For example, a network on amotherboard can be created with a printed circuit board, wireless dataconnections, and/or other types of network connections. Some logicalconnections are not shown for clarity. For example, connections withpower supplies and/or computer readable memory may not be shown forclarities sake, as many or all elements of a particular component mayneed to be connected to the power supplies and/or computer readablememory.

FIG. 4A is a block diagram of an example of a data processing system 400that can be associated with a bed system, including those describedabove with respect to FIGS. 1-3. This system 400 includes a pumpmotherboard 402 and a pump daughterboard 404. The system 400 includes asensor array 406 that can include one or more sensors configured tosense physical phenomenon of the environment and/or bed, and to reportsuch sensing back to the pump motherboard 402 for, for example,analysis. The system 400 also includes a controller array 408 that caninclude one or more controllers configured to control logic-controlleddevices of the bed and/or environment. The pump motherboard 400 can bein communication with one or more computing devices 414 and one or morecloud services 410 over local networks, the Internet 412, or otherwiseas is technically appropriate. Each of these components will bedescribed in more detail, some with multiple example configurations,below.

In this example, a pump motherboard 402 and a pump daughterboard 404 arecommunicably coupled. They can be conceptually described as a center orhub of the system 400, with the other components conceptually describedas spokes of the system 400. In some configurations, this can mean thateach of the spoke components communicates primarily or exclusively withthe pump motherboard 402. For example, a sensor of the sensor array maynot be configured to, or may not be able to, communicate directly with acorresponding controller. Instead, each spoke component can communicatewith the motherboard 402. The sensor of the sensor array 406 can reporta sensor reading to the motherboard 402, and the motherboard 402 candetermine that, in response, a controller of the controller array 408should adjust some parameters of a logic controlled device or otherwisemodify a state of one or more peripheral devices. In one case, if thetemperature of the bed is determined to be too hot, the pump motherboard402 can determine that a temperature controller should cool the bed.

One advantage of a hub-and-spoke network configuration, sometimes alsoreferred to as a star-shaped network, is a reduction in network trafficcompared to, for example, a mesh network with dynamic routing. If aparticular sensor generates a large, continuous stream of traffic, thattraffic may only be transmitted over one spoke of the network to themotherboard 402. The motherboard 402 can, for example, marshal that dataand condense it to a smaller data format for retransmission for storagein a cloud service 410. Additionally or alternatively, the motherboard402 can generate a single, small, command message to be sent down adifferent spoke of the network in response to the large stream. Forexample, if the large stream of data is a pressure reading that istransmitted from the sensor array 406 a few times a second, themotherboard 402 can respond with a single command message to thecontroller array to increase the pressure in an air chamber. In thiscase, the single command message can be orders of magnitude smaller thanthe stream of pressure readings.

As another advantage, a hub-and-spoke network configuration can allowfor an extensible network that can accommodate components being added,removed, failing, etc. This can allow, for example, more, fewer, ordifferent sensors in the sensor array 406, controllers in the controllerarray 408, computing devices 414, and/or cloud services 410. Forexample, if a particular sensor fails or is deprecated by a newerversion of the sensor, the system 400 can be configured such that onlythe motherboard 402 needs to be updated about the replacement sensor.This can allow, for example, product differentiation where the samemotherboard 402 can support an entry level product with fewer sensorsand controllers, a higher value product with more sensors andcontrollers, and customer personalization where a customer can add theirown selected components to the system 400.

Additionally, a line of air bed products can use the system 400 withdifferent components. In an application in which every air bed in theproduct line includes both a central logic unit and a pump, themotherboard 402 (and optionally the daughterboard 404) can be designedto fit within a single, universal housing. Then, for each upgrade of theproduct in the product line, additional sensors, controllers, cloudservices, etc., can be added. Design, manufacturing, and testing timecan be reduced by designing all products in a product line from thisbase, compared to a product line in which each product has a bespokelogic control system.

Each of the components discussed above can be realized in a wide varietyof technologies and configurations. Below, some examples of eachcomponent will be further discussed. In some alternatives, two or moreof the components of the system 400 can be realized in a singlealternative component; some components can be realized in multiple,separate components; and/or some functionality can be provided bydifferent components.

FIG. 4B is a block diagram showing some communication paths of the dataprocessing system 400. As previously described, the motherboard 402 andthe pump daughterboard 404 may act as a hub for peripheral devices andcloud services of the system 400. In cases in which the pumpdaughterboard 404 communicates with cloud services or other components,communications from the pump daughterboard 404 may be routed through thepump motherboard 402. This may allow, for example, the bed to have onlya single connection with the internet 412. The computing device 414 mayalso have a connection to the internet 412, possibly through the samegateway used by the bed and/or possibly through a different gateway(e.g., a cell service provider).

Previously, a number of cloud services 410 were described. As shown inFIG. 4B, some cloud services, such as cloud services 410 d and 410 e,may be configured such that the pump motherboard 402 can communicatewith the cloud service directly—that is the motherboard 402 maycommunicate with a cloud service 410 without having to use another cloudservice 410 as an intermediary. Additionally or alternatively, somecloud services 410, for example cloud service 410 f, may only bereachable by the pump motherboard 402 through an intermediary cloudservice, for example cloud service 410 e. While not shown here, somecloud services 410 may be reachable either directly or indirectly by thepump motherboard 402.

Additionally, some or all of the cloud services 410 may be configured tocommunicate with other cloud services. This communication may includethe transfer of data and/or remote function calls according to anytechnologically appropriate format. For example, one cloud service 410may request a copy for another cloud service's 410 data, for example,for purposes of backup, coordination, migration, or for performance ofcalculations or data mining. In another example, many cloud services 410may contain data that is indexed according to specific users tracked bythe user account cloud 410 c and/or the bed data cloud 410 a. Thesecloud services 410 may communicate with the user account cloud 410 cand/or the bed data cloud 410 a when accessing data specific to aparticular user or bed.

FIG. 5 is a block diagram of an example of a motherboard 402 that can beused in a data processing system that can be associated with a bedsystem, including those described above with respect to FIGS. 1-3. Inthis example, compared to other examples described below, thismotherboard 402 consists of relatively fewer parts and can be limited toprovide a relatively limited feature set.

The motherboard includes a power supply 500, a processor 502, andcomputer memory 512. In general, the power supply includes hardware usedto receive electrical power from an outside source and supply it tocomponents of the motherboard 402. The power supply can include, forexample, a battery pack and/or wall outlet adapter, an AC to DCconverter, a DC to AC converter, a power conditioner, a capacitor bank,and/or one or more interfaces for providing power in the current type,voltage, etc., needed by other components of the motherboard 402.

The processor 502 is generally a device for receiving input, performinglogical determinations, and providing output. The processor 502 can be acentral processing unit, a microprocessor, general purpose logiccircuitry, application-specific integrated circuitry, a combination ofthese, and/or other hardware for performing the functionality needed.

The memory 512 is generally one or more devices for storing data. Thememory 512 can include long term stable data storage (e.g., on a harddisk), short term unstable (e.g., on Random Access Memory) or any othertechnologically appropriate configuration.

The motherboard 402 includes a pump controller 504 and a pump motor 506.The pump controller 504 can receive commands from the processor 502 and,in response, control the function of the pump motor 506. For example,the pump controller 504 can receive, from the processor 502, a commandto increase the pressure of an air chamber by 0.3 pounds per square inch(PSI). The pump controller 504, in response, engages a valve so that thepump motor 506 is configured to pump air into the selected air chamber,and can engage the pump motor 506 for a length of time that correspondsto 0.3 PSI or until a sensor indicates that pressure has been increasedby 0.3 PSI. In an alternative configuration, the message can specifythat the chamber should be inflated to a target PSI, and the pumpcontroller 504 can engage the pump motor 506 until the target PSI isreached.

A valve solenoid 508 can control which air chamber a pump is connectedto. In some cases, the solenoid 508 can be controlled by the processor502 directly. In some cases, the solenoid 508 can be controlled by thepump controller 504.

A remote interface 510 of the motherboard 402 can allow the motherboard402 to communicate with other components of a data processing system.For example, the motherboard 402 can be able to communicate with one ormore daughterboards, with peripheral sensors, and/or with peripheralcontrollers through the remote interface 510. The remote interface 510can provide any technologically appropriate communication interface,including but not limited to multiple communication interfaces such asWiFi, Bluetooth, and copper wired networks.

FIG. 6 is a block diagram of an example of a motherboard 402 that can beused in a data processing system that can be associated with a bedsystem, including those described above with respect to FIGS. 1-3.Compared to the motherboard 402 described with reference to FIG. 5, themotherboard in FIG. 6 can contain more components and provide morefunctionality in some applications.

In addition to the power supply 500, processor 502, pump controller 504,pump motor 506, and valve solenoid 508, this motherboard 402 is shownwith a valve controller 600, a pressure sensor 602, a universal serialbus (USB) stack 604, a WiFi radio 606, a Bluetooth Low Energy (BLE)radio 608, a ZigBee radio 610, a Bluetooth radio 612 and a computermemory 512.

Similar to the way that the pump controller 504 converts commands fromthe processor 502 into control signals for the pump motor 506, the valvecontroller 600 can convert commands from the processor 502 into controlsignals for the valve solenoid 508. In one example, the processor 502can issue a command to the valve controller 600 to connect the pump to aparticular air chamber out of the group of air chambers in an air bed.The valve controller 600 can control the position of the valve solenoid508 so that the pump is connected to the indicated air chamber.

The pressure sensor 602 can read pressure readings from one or more airchambers of the air bed. The pressure sensor 602 can also preformdigital sensor conditioning.

The motherboard 402 can include a suite of network interfaces, includingbut not limited to those shown here. These network interfaces can allowthe motherboard to communicate over a wired or wireless network with anynumber of devices, including but not limited to peripheral sensors,peripheral controllers, computing devices, and devices and servicesconnected to the Internet 412.

FIG. 7 is a block diagram of an example of a daughterboard 404 that canbe used in a data processing system that can be associated with a bedsystem, including those described above with respect to FIGS. 1-3. Insome configurations, one or more daughterboards 404 can be connected tothe motherboard 402. Some daughterboards 404 can be designed to offloadparticular and/or compartmentalized tasks from the motherboard 402. Thiscan be advantageous, for example, if the particular tasks arecomputationally intensive, proprietary, or subject to future revisions.For example, the daughterboard 404 can be used to calculate a particularsleep data metric. This metric can be computationally intensive, andcalculating the sleep metric on the daughterboard 404 can free up theresources of the motherboard 402 while the metric is being calculated.Additionally and/or alternatively, the sleep metric can be subject tofuture revisions. To update the system 400 with the new sleep metric, itis possible that only the daughterboard 404 that calculates that metricneed be replaced. In this case, the same motherboard 402 and othercomponents can be used, saving the need to perform unit testing ofadditional components instead of just the daughterboard 404.

The daughterboard 404 is shown with a power supply 700, a processor 702,computer readable memory 704, a pressure sensor 706, and a WiFi radio708. The processor can use the pressure sensor 706 to gather informationabout the pressure of the air chamber or chambers of an air bed. Fromthis data, the processor 702 can perform an algorithm to calculate asleep metric. In some examples, the sleep metric can be calculated fromonly the pressure of air chambers. In other examples, the sleep metriccan be calculated from one or more other sensors. In an example in whichdifferent data is needed, the processor 702 can receive that data froman appropriate sensor or sensors. These sensors can be internal to thedaughterboard 404, accessible via the WiFi radio 708, or otherwise incommunication with the processor 702. Once the sleep metric iscalculated, the processor 702 can report that sleep metric to, forexample, the motherboard 402.

FIG. 8 is a block diagram of an example of a motherboard 800 with nodaughterboard that can be used in a data processing system that can beassociated with a bed system, including those described above withrespect to FIGS. 1-3. In this example, the motherboard 800 can performmost, all, or more of the features described with reference to themotherboard 402 in FIG. 6 and the daughterboard 404 in FIG. 7.

FIG. 9 is a block diagram of an example of a sensory array 406 that canbe used in a data processing system that can be associated with a bedsystem, including those described above with respect to FIGS. 1-3. Ingeneral, the sensor array 406 is a conceptual grouping of some or allthe peripheral sensors that communicate with the motherboard 402 but arenot native to the motherboard 402.

The peripheral sensors of the sensor array 406 can communicate with themotherboard 402 through one or more of the network interfaces of themotherboard, including but not limited to the USB stack 604, a WiFiradio 606, a Bluetooth Low Energy (BLE) radio 608, a ZigBee radio 610,and a Bluetooth radio 612, as is appropriate for the configuration ofthe particular sensor. For example, a sensor that outputs a reading overa USB cable can communicate through the USB stack 604.

Some of the peripheral sensors 900 of the sensor array 406 can be bedmounted 900. These sensors can be, for example, embedded into thestructure of a bed and sold with the bed, or later affixed to thestructure of the bed. Other peripheral sensors 902 and 904 can be incommunication with the motherboard 402, but optionally not mounted tothe bed. In some cases, some or all of the bed mounted sensors 900and/or peripheral sensors 902 and 904 can share networking hardware,including a conduit that contains wires from each sensor, a multi-wirecable or plug that, when affixed to the motherboard 402, connect all ofthe associated sensors with the motherboard 402. In some embodiments,one, some, or all of sensors 902, 904, 906, 908, and 910 can sense oneor more features of a mattress, such as pressure, temperature, light,sound, and/or one or more other features of the mattress. In someembodiments, one, some, or all of sensors 902, 904, 906, 908, and 910can sense one or more features external to the mattress. In someembodiments, pressure sensor 902 can sense pressure of the mattresswhile some or all of sensors 902, 904, 906, 908, and 910 can sense oneor more features of the mattress and/or external to the mattress.

FIG. 10 is a block diagram of an example of a controller array 408 thatcan be used in a data processing system that can be associated with abed system, including those described above with respect to FIGS. 1-3.In general, the controller array 408 is a conceptual grouping of some orall peripheral controllers that communicate with the motherboard 402 butare not native to the motherboard 402.

The peripheral controllers of the controller array 408 can communicatewith the motherboard 402 through one or more of the network interfacesof the motherboard, including but not limited to the USB stack 604, aWiFi radio 606, a Bluetooth Low Energy (BLE) radio 608, a ZigBee radio610, and a Bluetooth radio 612, as is appropriate for the configurationof the particular sensor.

These applications can allow a user toview information about the bed (e.g., sensor readings, sleep metrics),or configure the behavior of the system 400 (e.g., set a desiredfirmness to the bed, set desired behavior for peripheral devices). Insome cases, the computing device 412 can be used in addition to, or toreplace, the remote control 122 described previously.

FIG. 12 is a block diagram of an example bed data cloud service 410 athat can be used in a data processing system that can be associated witha bed system, including those described above with respect to FIGS. 1-3.In this example, the bed data cloud service 410 a is configured tocollect sensor data and sleep data from a particular bed, and to matchthe sensor and sleep data with one or more users that use the bed whenthe sensor and sleep data was generated.

The bed data cloud service 410 a is shown with a network interface 1200,a communication manager 1202, server hardware 1204, and server systemsoftware 1206. In addition, the bed data cloud service 410 a is shownwith a user identification module 1208, a device management 1210 module,a sensor data module 1210, and an advanced sleep data module 1214.

The network interface 1200 generally includes hardware and low levelsoftware used to allow one or more hardware devices to communicate overnetworks. For example the network interface 1200 can include networkcards, routers, modems, and other hardware needed to allow thecomponents of the bed data cloud service 410 a to communicate with eachother and other destinations over, for example, the Internet 412. Thecommunication manger 1202 generally comprises hardware and software thatoperate above the network interface 1200. This includes software toinitiate, maintain, and tear down network communications used by the beddata cloud service 410 a. This includes, for example, TCP/IP, SSL orTLS, Torrent, and other communication sessions over local or wide areanetworks. The communication manger 1202 can also provide load balancingand other services to other elements of the bed data cloud service 410a.

The server hardware 1204 generally includes the physical processingdevices used to instantiate and maintain bed data cloud service 410 a.This hardware includes, but is not limited to processors (e.g., centralprocessing units, ASICs, graphical processers), and computer readablememory (e.g., random access memory, stable hard disks, tape backup). Oneor more servers can be configured into clusters, multi-computer, ordatacenters that can be geographically separate or connected.

The server system software 1206 generally includes software that runs onthe server hardware 1204 to provide operating environments toapplications and services.

The user identification 1208 can include, or reference, data related tousers of beds with associated data processing systems. For example, theusers can include customers, owners, or other users registered with thebed data cloud service 410 a or another service. Each user can have, forexample, a unique identifier, user credentials, contact information,billing information, demographic information, or any othertechnologically appropriate information.

The device manager 1210 can include, or reference, data related to bedsor other products associated with data processing systems. For example,the beds can include products sold or registered with a systemassociated with the bed data cloud service 410 a. Each bed can have, forexample, a unique identifier, model and/or serial number, salesinformation, geographic information, delivery information, a listing ofassociated sensors and control peripherals, etc. Additionally, an indexor indexes stored by the bed data cloud service 410 a can identify usersthat are associated with beds. For example, this index can record salesof a bed to a user, users that sleep in a bed, etc.

The sensor data 1212 can record raw or condensed sensor data recorded bybeds with associated data processing systems. For example, a bed's dataprocessing system can have a temperature sensor, pressure sensor, andlight sensor. Readings from these sensors, either in raw form or in aformat generated from the raw data (e.g. sleep metrics) of the sensors,can be communicated by the bed's data processing system to the bed datacloud service 410 a for storage in the sensor data 1212. Additionally,an index or indexes stored by the bed data cloud service 410 a canidentify users and/or beds that are associated with the sensor data1212.

The bed data cloud service 410 a can use any of its available data togenerate advanced sleep data 1214. In general, the advanced sleep data1214 includes sleep metrics and other data generated from sensorreadings. Some of these calculations can be performed in the bed datacloud service 410 a instead of locally on the bed's data processingsystem, for example, because the calculations are computationallycomplex or require a large amount of memory space or processor powerthat is not available on the bed's data processing system. This can helpallow a bed system to operate with a relatively simple controller andstill be part of a system that performs relatively complex tasks andcomputations.

FIG. 13 is a block diagram of an example sleep data cloud service 410 bthat can be used in a data processing system that can be associated witha bed system, including those described above with respect to FIGS. 1-3.In this example, the sleep data cloud service 410 b is configured torecord data related to users' sleep experience.

The purchase information can include, for example, data of a sale,price, and location of sale, delivery address, and configuration optionsselected by the users at the time of sale. These configuration optionscan include selections made by the user about how they wish their newlypurchased beds to be setup and can include, for example, expected sleepschedule, a listing of peripheral sensors and controllers that they haveor will install, etc.

The bed setup module 1514 can include, or reference, data related toinstallations of beds that users' purchase. The bed setup data caninclude, for example, the date and address to which a bed is delivered,the person that accepts delivery, the configuration that is applied tothe bed upon delivery, the name or names of the person or people whowill sleep on the bed, which side of the bed each person will use, etc.

Data recorded in the point of sale cloud service 1500 can be referencedby a user's bed system at later dates to control functionality of thebed system and/or to send control signals to peripheral componentsaccording to data recorded in the point of sale cloud service 1500. Thiscan allow a salesperson to collect information from the user at thepoint of sale that later facilitates automation of the bed system. Insome examples, some or all aspects of the bed system can be automatedwith little or no user-entered data required after the point of sale. Inother examples, data recorded in the point of sale cloud service 1500can be used in connection with a variety of additional data gatheredfrom user-entered data.

FIG. 16 is a block diagram of an example environment cloud service 1600that can be used in a data processing system that can be associated witha bed system, including those described above with respect to FIGS. 1-3.In this example, the environment cloud service 1600 is configured torecord data related to users' home environment.

The environment cloud service 1600 is shown with a network interface1602, a communication manager 1604, server hardware 1606, and serversystem software 1608. In addition, the environment cloud service 1600 isshown with a user identification module 1610, an environmental sensormodule 1612, and an environmental factors module 1614.

The environmental sensors module 1612 can include a listing of sensorsthat users' in the user identification module 1610 have installed intheir bed.

The environmental factors module 1614 can include reports generatedbased on data in the environmental sensors module 1612. For example, fora user with a light sensor with data in the environment sensors module1612, the environmental factors module 1614 can hold a report indicatingthe frequency and duration of instances of increased lighting when theuser is asleep.

In the examples discussed here, each cloud service 410 is shown withsome of the same components. In various configurations, these samecomponents can be partially or wholly shared between services, or theycan be separate. In some configurations, each service can have separatecopies of some or all of the components that are the same or differentin some ways. Additionally, these components are only supplied asillustrative examples. In other examples each cloud service can havedifferent number, types, and styles of components that are technicallypossible.

FIG. 17 is a block diagram of an example of using a data processingsystem that can be associated with a bed (such as a bed of the bedsystems described herein) to automate peripherals around the bed. Shownhere is a behavior analysis module 1700 that runs on the pumpmotherboard 402. For example, the behavior analysis module 1700 can beone or more software components stored on the computer memory 512 andexecuted by the processor 502. In general, the behavior analysis module1700 can collect data from a wide variety of sources (e.g., sensors,non-sensor local sources, cloud data services) and use a behavioralalgorithm 1702 to generate one or more actions to be taken (e.g.,commands to send to peripheral controllers, data to send to cloudservices). This can be useful, for example, in tracking user behaviorand automating devices in communication with the user's bed.

The behavior analysis module 1700 can collect data from anytechnologically appropriate source, for example, to gather data aboutfeatures of a bed, the bed's environment, and/or the bed's users. Somesuch sources include any of the sensors of the sensor array 406. Forexample, this data can provide the behavior analysis module 1700 withinformation about the current state of the environment around the bed.For example, the behavior analysis module 1700 can access readings fromthe pressure sensor 902 to determine the pressure of an air chamber inthe bed. From this reading, and potentially other data, user presence inthe bed can be determined. In another example, the behavior analysismodule can access a light sensor 908 to detect the amount of light inthe bed's environment.

Similarly, the behavior analysis module 1700 can access data from cloudservices. For example, the behavior analysis module 1700 can access thebed cloud service 410 a to access historical sensor data 1212 and/oradvanced sleep data 1214. Other cloud services 410, including those notpreviously described can be accessed by the behavior analysis module1700. For example, the behavior analysis module 1700 can access aweather reporting service, a 3rd party data provider (e.g., traffic andnews data, emergency broadcast data, user travel data), and/or a clockand calendar service.

Similarly, the behavior analysis module 1700 can access data fromnon-sensor sources 1704. For example, the behavior analysis module 1700can access a local clock and calendar service (e.g., a component of themotherboard 402 or of the processor 502).

The behavior analysis module 1700 can aggregate and prepare this datafor use by one or more behavioral algorithms 1702. The behavioralalgorithms 1702 can be used to learn a user's behavior and/or to performsome action based on the state of the accessed data and/or the predicteduser behavior. For example, the behavior algorithm 1702 can useavailable data (e.g., pressure sensor, non-sensor data, clock andcalendar data) to create a model of when a user goes to bed every night.Later, the same or a different behavioral algorithm 1702 can be used todetermine if an increase in air chamber pressure is likely to indicate auser going to bed and, if so, send some data to a third-party cloudservice 410 and/or engage a peripheral controller 1002.

In the example shown, the behavioral analysis module 1700 and thebehavioral algorithm 1702 are shown as components of the motherboard402. However, other configurations are possible. For example, the sameor a similar behavioral analysis module and/or behavior algorithm can berun in one or more cloud services, and the resulting output can be sentto the motherboard 402, a controller in the controller array 408, or toany other technologically appropriate recipient.

The computer program product can also be tangiblyembodied in a computer- or machine-readable medium, such as the memory1804, the storage device 1806, or memory on the processor 1802.

The high-speed interface 1808 manages bandwidth-intensive operations forthe computing device 1800, while the low-speed interface 1812 manageslower bandwidth-intensive operations. Such allocation of functions isexemplary only. In some implementations, the high-speed interface 1808is coupled to the memory 1804, the display 1816 (e.g., through agraphics processor or accelerator), and to the high-speed expansionports 1810, which can accept various expansion cards (not shown). In theimplementation, the low-speed interface 1812 is coupled to the storagedevice 1806 and the low-speed expansion port 1814.

The computing device 1800 can be implemented in a number of differentforms, as shown in the figure. For example, it can be implemented as astandard server 1820, or multiple times in a group of such servers. Inaddition, it can be implemented in a personal computer such as a laptopcomputer 1822. It can also be implemented as part of a rack serversystem 1824. Alternatively, components from the computing device 1800can be combined with other components in a mobile device (not shown),such as a mobile computing device 1850. Each of such devices can containone or more of the computing device 1800 and the mobile computing device1850, and an entire system can be made up of multiple computing devicescommunicating with each other.

The mobile computing device 1850 includes a processor 1852, a memory1864, an input/output device such as a display 1854, a communicationinterface 1866, and a transceiver 1868, among other components. Themobile computing device 1850 can also be provided with a storage device,such as a micro-drive or other device, to provide additional storage.Each of the processor 1852, the memory 1864, the display 1854, thecommunication interface 1866, and the transceiver 1868, areinterconnected using various buses, and several of the components can bemounted on a common motherboard or in other manners as appropriate.

The processor 1852 can execute instructions within the mobile computingdevice 1850, including instructions stored in the memory 1864. Theprocessor 1852 can be implemented as a chipset of chips that includeseparate and multiple analog and digital processors. The processor 1852can provide, for example, for coordination of the other components ofthe mobile computing device 1850, such as control of user interfaces,applications run by the mobile computing device 1850, and wirelesscommunication by the mobile computing device 1850.

The processor 1852 can communicate with a user through a controlinterface 1858 and a display interface 1856 coupled to the display 1854.The display 1854 can be, for example, a TFT (Thin-Film-Transistor LiquidCrystal Display) display or an OLED (Organic Light Emitting Diode)display, or other appropriate display technology. The display interface1856 can comprise appropriate circuitry for driving the display 1854 topresent graphical and other information to a user.

An expansion memory 1874 can also beprovided and connected to the mobile computing device 1850 through anexpansion interface 1872, which can include, for example, a SIMM (SingleIn Line Memory Module) card interface. The expansion memory 1874 canprovide extra storage space for the mobile computing device 1850, or canalso store applications or other information for the mobile computingdevice 1850. Specifically, the expansion memory 1874 can includeinstructions to carry out or supplement the processes described above,and can include secure information also. Thus, for example, theexpansion memory 1874 can be provide as a security module for the mobilecomputing device 1850, and can be programmed with instructions thatpermit secure use of the mobile computing device 1850. In addition,secure applications can be provided via the SIMM cards, along withadditional information, such as placing identifying information on theSIMM card in a non-hackable manner.

The memory can include, for example, flash memory and/or NVRAM memory(non-volatile random access memory), as discussed below. In someimplementations, a computer program product is tangibly embodied in aninformation carrier. The computer program product contains instructionsthat, when executed, perform one or more methods, such as thosedescribed above. The computer program product can be a computer- ormachine-readable medium, such as the memory 1864, the expansion memory1874, or memory on the processor 1852. In some implementations, thecomputer program product can be received in a propagated signal, forexample, over the transceiver 1868 or the external interface 1862.

The mobile computing device 1850 can communicate wirelessly through thecommunication interface 1866, which can include digital signalprocessing circuitry where necessary. The communication interface 1866can provide for communications under various modes or protocols, such asGSM voice calls (Global System for Mobile communications), SMS (ShortMessage Service), EMS (Enhanced Messaging Service), or MMS messaging(Multimedia Messaging Service), CDMA (code division multiple access),TDMA (time division multiple access), PDC (Personal Digital Cellular),WCDMA (Wideband Code Division Multiple Access), CDMA2000, or GPRS(General Packet Radio Service), among others. Such communication canoccur, for example, through the transceiver 1868 using aradio-frequency. In addition, short-range communication can occur, suchas using a Bluetooth, WiFi, or other such transceiver (not shown). Inaddition, a GPS (Global Positioning System) receiver module 1870 canprovide additional navigation- and location-related wireless data to themobile computing device 1850, which can be used as appropriate byapplications running on the mobile computing device 1850.

The mobile computing device 1850 can also communicate audibly using anaudio codec 1860, which can receive spoken information from a user andconvert it to usable digital information. The audio codec 1860 canlikewise generate audible sound for a user, such as through a speaker,e.g., in a handset of the mobile computing device 1850. Such sound caninclude sound from voice telephone calls, can include recorded sound(e.g., voice messages, music files, etc.) and can also include soundgenerated by applications operating on the mobile computing device 1850.

The computing system can include clients and servers. A client andserver are generally remote from each other and typically interactthrough a communication network. The relationship of client and serverarises by virtue of computer programs running on the respectivecomputers and having a client-server relationship to each other.

FIG. 19 is a flowchart of method 1900 to monitor and adjust pressure ofan air mattress, according to various examples. For labeling purposes,and not by way of limitation, method 1900 is referred to herein as an“auto-adjust” method or feature. While many of the operations of method1900 are described as being performed on data processing system 400,other components may be used. For example, the control box 124 can storethe preferences and determine if the auto-adjust feature should beengaged as further described below. In various examples, data processingsystem 400 can act as a relay of the preferences as describedpreviously.

At block 1902, in various examples, user preferences related to theauto-adjust method are received at data processing system 400. Thepreferences may be received from one or more of remotes 122, thecomputing device 414, or a cloud service 410. For example, using anapplication running on the computing device 414, a user interface (UI)may be presented to the user. The UI may include input indicia (checkboxes, radio buttons, input forms, etc.) for the preferences related tothe auto-adjust method. A user may interact (e.g., click, activate) withthe input indicia to set the preferences. The preferences may be storedin a storage device of the computing device 414 and/or be transmitted tothe pump motherboard 402 for storage, such as within a memory 512. Invarious examples, the preferences may be stored in a database(relational, non-relational, flat file, etc.) or in a structured file(e.g., XML), for example in a cloud service 410 such as the devicemanager 1210 of the bed data cloud 410 a. The preferences may also havedefault, pre-set values if the user does not input a value. In variousexamples, not all of the preferences are shown to a user.

In various examples, there may be a global enablement preference for theauto-adjust feature. In an example, the enabling preference is a Booleanrepresenting the user's preference to use the auto-adjust feature in anycontext. For example, if the preference is not set, the air mattresssystem may forego adjusting the pressure except when manually adjustedby a user control. The global enablement preference may also allow theuser to select between an option that utilizes pre-set user preferencesfor pressure adjustment and an option that utilizes a “learning”procedure as described in further detail below.

In various examples, in addition to a global enablement preference,there may be sub-preferences of when automatic adjustments may occur.These may include, but are not limited to, a presence preference, asleep cycle preference, a sleep position preference, and a timepreference.

While multiple preferences are described, various examples may use lessthan all the preferences. For example, only the enabling preference maybe used. If the enabling preference indicates that the user does notwant to use the auto-adjust feature, one or more of the remainingpreferences may not be shown or not be set (e.g., shown as dimmedoptions) by the user.

In some examples, the presence preference indicates when automaticpressure adjustments may be made with respect to the presence of aperson on the air mattress. For example, there may be an on-bedadjustment preference and an off-bed adjustment preference that when setindicate whether pressure adjustments may be made to the air mattresswhen someone is on and off the bed, respectively.

In some examples, the sleep cycle preference indicates when automaticpressure adjustments may be made with respect to the current sleep stateof a user. For example, a preference may be set that indicates thatchanges may be made when the user is on the bed, but not currentlyasleep. Other preferences may include only changing the pressure whenthe user is in a certain sleep state (e.g. REM or deep sleep), or in acertain sleep position. A preference may be displayed for each stage ofsleep and non-sleep to allow the user greater flexibility of whenpressure adjustments may occur.

In some examples, the time preference may be set by a user to indicateone or more time periods of day when the auto-adjust feature can orcannot be engaged. For example, the user may indicate that from 9:00 AMto 5:00 PM the auto-adjust feature may be used. Thus, if during the settime period other auto-adjust conditions are met (further discussedbelow), then the auto-adjust feature may be engaged. If the conditionsare otherwise met, but the current time of day is not within the user'sdefined period, auto-adjustment may not occur.

In various examples, one or more pressure settings of the air mattresscan be pre-set by the user and stored in memory, including, but notlimited to, the user's preferred pressure setting for each of one ormore sleeping positions, such as when the user is lying on his or herback, side, or stomach. For example, a user may indicate, with anumerical value, a desired firmness setting to be implemented when theuser sleeps on his or her back, a second desired firmness setting to beimplemented when the user sleeps on his or her side, and a third desiredfirmness setting to be implemented when the user sleeps on his or herstomach. Instead of using default, pre-set values or user-definedpreferences.

In various examples, the system can be configured to automaticallydetermine what sleeping position a user is in based on measurements fromone or more of the pressure sensor, the motion sensor, or thetemperature sensor. As noted above, a pressure sensor (e.g., pressuresensor 602) can be sufficiently sensitive so that the data processingsystem 400 can determine motion by the user. The pressure sensor and thedata processing system 400 can also be configured to determine whichposition the user is in. For example, in general, when a user changesfrom lying on his or her back to lying on his or her side, there is apressure change in the air chambers associated with that, typically anincrease in pressure because the user's shoulder tends to push down withmore force into the bed when the user is lying on his or her side. Thedetermination of whether a user is lying on his or her back, side, orfront can be determined based on historical data (e.g., a databasecompiled by the system manufacturer), or a user can “teach” the systemwhen he or she is lying in each position. For example, the system can beconfigured to go into a specific learning mode that instructs the userto lie on his or her back for a specified period while the systemmeasures the pressure associated with the user on his or her back, thenshift to his or her side (or front) for another period of time while thesystem measures the pressure associated with the user on his or herside, and then shift to his or her front and measure the pressureassociated with the user on his or her front. The historical data baseor the user-specific data regarding sleep positions, or both, can bestored in a memory of the system for later access.

The system can also utilize a “learning” process to automaticallyspecify various pressure settings of the air mattress when the usersleeps on his or her back, side, or stomach, respectively. See, forexample, FIG. 17. The automatic pressure settings can be set in orderfor the user to more easily achieve a particular sleep state (e.g., REMsleep or deep sleep) at a particular time or range of times. Forexample, as described above, the data processing system 400 candetermine if a user is sleeping on his or her front, side, or back, andthen can modify the pressure in the air chamber or chambers over timeand record the effect on the user's sleep state (e.g., if the pressuresetting improves the user's sleep, such as by allowing the user to reachREM sleep more easily). The system can be configured to relativelycontinuously experiment with pressure settings over time (if allowed bythe user) in order to learn the most effective setting for each sleepposition to achieve a desired sleep state for the user (e.g., REM sleepor deep sleep). The system can repeat this learning experimentation foreach sleep position.

In yet another example, the data processing system 400 can be configuredto continually monitor the user's sleep state (e.g., by measuring andanalyzing heart rate, respiration rate, and motion, as described above),and continuously or semi-continuously modifying the pressure settingwithin the air chamber or chambers based on the monitored sleep state,e.g., as a feedback loop.

The sleep state that the system will attempt to achieve for the user candepend on specific parameters provided by the user, such as the time ofnight. The user can set a time range for which one or more sleep statesare desired, and the system can adjust the pressure setting to achievethat sleep state. For example, the user can indicate that from 10:00 PMto 5:00 AM, an REM sleep state is preferred and the system can adjustthe pressure in the air chamber (or the temperature experienced by theuser) to optimize the user's ability to achieve REM sleep (e.g., basedon one or more of the user's sleeping position, the user's enteredpreferences, the learned settings, and a feedback based adjustment). Inanother example, the user can select a particular wake-up time, or rangeof wake-up times, and the system can adjust the pressure or temperature,or both, to gradually wake the user up at the desired time. The systemcan also be configured to determine, based on the user's heart rate,respiration rate, and movement, when the user is at an optimized pointin his or her sleep cycle for waking up (within the user's selectedwake-up time range) and attempt to wake the user up at that time. Thesystem can also be in communication with another device, such as analarm or a mobile device, to initiate an alarm (such as an alarm sound)when the user is at the optimized wake-up point.

Similar configuration of the system can be made for adjustingtemperature, including the user providing a preferred temperature forcertain types of sleep or certain times and the system learning whattemperature settings can provide for a particular sleep state (e.g., ata particular time).

In various examples, one or more pressure settings of the air mattresscan be learned for the user (1904). The learned pressures may be used todetermine if adjustments should be made to the pressure level in the airmattress system customized for the user's behavior, environment,sleeping position (e.g., back or side), or other sleeping preferences.For example, a user may initially indicate, with a numerical value, adesired firmness setting. At this time, the air mattress system maystore the actual PSI level of the air mattress as a base pressure level.Over a period of time(s) the pressure in the air mattress may bemonitored (e.g., via the transducer of the air mattress) to determinechanges to the base pressure level.

The learned pressure levels may be collected and organized in a varietyof matters. For example, the learned pressure levels may be correlatedwith a time of the day, presence of a person on the air mattress,position of the person, sleep state, quality or length of sleep state,or combinations thereof. The learned pressure levels may be taken over alearning period of a number of days or other period (e.g., one or moreweeks) to obtain average pressure levels based on the aboveorganizations. A table, file, or other data structure may be stored thatcorrelates the time with a pressure level.

In some examples, a series of pressure levels may be taken over pre-settimes during the day. For example, a pressure setting may be taken every6 hours (e.g., midnight, 6:00 AM, noon, 6:00 PM). The taken pressuresettings can be stored in a table or other data structure and correlatedwith the time. Thus, after three full days of monitoring at six-hourintervals, there would be 12 total pressure readings. For each of thepre-set times, the pressure readings at that time can be averaged todetermine an average learned pressure for that pre-set time.

Other variations of averaging may also be used. For example, there maybe different pressure levels based on if someone is on the bed or not.Thus, a pressure reading at noon one day may be different than a readingtaken at noon on the second day. To account for such variations,pressure readings taken at the pre-set times may be clustered orbucketed into groups which may serve as a proxy for presence in the bed.For example, the pressure readings may be grouped into two groups. As abasis of determining which group a pressure reading is placed in, thepressure reading may be compared to the base pressure reading.Accordingly, if a taken pressure reading is within a threshold (e.g., 1PSI), the pressure reading may be grouped with the base pressurereading. If the pressure reading is outside of the threshold it may beplaced into a second group. Consequently, at the end of the learningperiod, for each pre-set time there may be two averaged pressurereadings. More than two groups of pressure readings may also be usedwithout departing the scope of this disclosure.

In some examples, the pressure readings can be grouped according to thepresence of a person in the bed. For example, during the learning periodat each of the pre-set times, data processing system 400 may receive anindication that nobody is on an air mattress. The indication may bereceived from a variety of sources. For example, pressure sensor 602 maymonitor the pressure of the air mattress and if a pressure changeexceeds a threshold, pump controller 504 may classify the change as an“empty bed” event—the label “empty bed” is used for illustrationpurposes only and other terms may be used without departing from thescope of this disclosure. In various examples, data processing system400 may receive an indication from a cloud service 410, sensor of thesensor array 406, or computing device 414 that an “empty bed” has beendetected. For example, the pressure readings from transducer 146 may beused to determine the presence of one or more people on the airmattress. Similarly, the pressure data may be transmitted to a cloudservice 410. Based on the processing the cloud service 410 may transmitdata back to data processing system 400 indicating whether or not aperson is believed to be on the air mattress.

In an example, data processing system 400 may detect user presence viagross pressure changes. For example, the pressure sensor 602 and/orpressure transducer 146 may be used to monitor the air pressure in theair mattress of a bed. If the user sits or lies down on the airmattress, the air pressure in the air mattress changes, e.g., increases,due to the additional weight of the user, which results in a grosspressure change. Data processing system 400 may determine whether theuser is now on the bed based on the gross pressure change, e.g., oversome time period. For example, by determining a rate of change ofpressure, e.g., over one to ten minutes, and comparing the determinedrate of change to a threshold value, data processing system 400 maydetermine whether the user is now on the bed.

In an example implementation, data processing system 400 may detect userpresence using one or more temperature changes detected in the airmattress, on a surface of the mattress, or a combination of the two. Theone or more temperature changes can be detected using one or moretemperature sensors 906 positioned in, on, or nearby the mattress. Theone or more temperature sensors 906 and the data processing system 400may detect a rise in temperature, e.g., over a specified period of time,and determine that a user is present in the bed. For example, if dataprocessing system 400 detects a rise in temperature and then determinesthat the detected rise in temperature was not caused by the system'stemperature controller 1006, data processing system 400 may determinethat the user is present. Any suitable temperature sensor can be used,as well as infrared camera technology configured to detect temperaturevariations at a particular point in time or over a specified period oftime.

In an example implementation, data processing system 400 may detect userpresence using motion detected in or on the mattress. Motion can bedetected, for example, using one or more motion sensors (see, e.g.,peripheral sensors 902 and 904) positioned in, on, or nearby themattress. The motion sensors and the data processing system 400 maydetect motion or a change in motion, e.g., over a specified period oftime, and determine that a user is present in the bed. For example, ifdata processing system 400 detects motion or a change in motionattributable to a user and determines that the detected motion was notcaused by the data processing system 400 (e.g., a peripheral controller1002 engaging a vibration device, the pump controller 504 engaging),data processing system 400 may determine that the user is present. Invarious examples, motion can be detected using motion sensors incombination with one or more additional sensors, such as temperaturesensors and pressure sensors. Alternatively, motion can be detectedwithout the use of motion sensors and based solely on other sensedparameters, such as temperature, pressure, or a combination of sensedtemperature and pressure.

The data processing system 400 can be configured to determine when auser is in a particular sleep state (such as rapid eye movement (REM)sleep, deep sleep, or restlessness). For example, as described above,the data processing system 400 can be configured to analyze readingsfrom one or more sensors, such as a pressure sensor (e.g., pressuretransducer) to determine a user's heart rate and respiration rate. Thedata processing system 400 can also analyze data from the pressuresensor, either alone or in combination with data from other sensors suchas a motion sensor, to detect and analyze motion of the user on the bed.The data processing system 400 can be configured to recognize aparticular sleep state based on one or more of the determined heartrate, respiration rate, and motion of the user. For example, when a useris in REM sleep, the heart rate and respiration rate are bothsubstantially reduced compared to most other sleep states, includingdeep sleep that is not REM sleep. Users also tend to have no largemuscle movement at all (other than the eyes). Thus, the data processingsystem 400 can be configured to recognize REM sleep by a heart ratebelow a REM heart rate threshold alone or in combination with arespiration rate below a REM respiration threshold, and/or incombination with a general lack of movement by the user. Techniques formonitoring a user's sleep using heart rate information, respiration rateinformation, and other user information are disclosed in U.S. PatentApplication Publication No. 2010/0170043 to Steven J. Young et al.,titled “APPARATUS FOR MONITORING VITAL SIGNS,” the entire content ofwhich is incorporated herein by reference.

In an example implementation, the data processing system 400 can executeinstructions that cause a pressure sensor, such as the pressuretransducer 146 or pressure sensor 602, to measure air pressure values ata predefined sample rate. The data processing system 400 can store thepressure signals in a memory device. Processing of the pressure signalscan be performed by the data processing system 400, or at a locationremote from the bed, e.g., at a cloud service 410 or elsewhere.Analyzing the pressure signals, as indicated above, the data processingsystem 400 can determine a user's sleep state, e.g., rapid eye movement(“REM”) or non-rapid eye movement (“NREM”), by using one or more of thebiometric parameters.

In some examples, a series of pressure levels can be taken duringvarious sleep states of the user (e.g. REM, deep sleep, orrestlessness). For example, a pressure setting may be taken when theuser is determined to be in REM sleep or in REM sleep for a certainamount of time. The taken pressure settings may be stored in a table orother data structure and correlated with the sleep state. Thus, after alearning period, such as three full days of monitoring, there will benumerous pressure readings related to when the user was in REM sleep.The pressure readings at that time can be averaged to determine anaverage learned pressure for that sleep state in order to make pressurelevels recommendations to the user.

As discussed above, preferences may be set so that the data processingsystem 400 will only allow pressure adjustments when the user is in acertain sleep state (e.g. REM or deep sleep). Similarly, preferences maybe displayed for each stage of sleep and non-sleep to allow the usergreater flexibility as to when pressure adjustments may occur. As alsodiscussed above, pressure, temperature or motion detection can be usedto determine whether a user is on or off of the bed, in addition to aposition of the user on the bed. However, in various examples,temperature detection may additionally or alternatively be used todetermine sleep state of one or more users. Particularly, bodytemperature changes can be correlated to the sleep state of users. In anexample, when a user first lies down on the bed and his or her presenceis detected via any suitable presence detection means (e.g., pressure,motion, or temperature), an initial body temperature measurement can betaken. As the user is lying on the bed, one or more temperature sensorscan continuously or periodically monitor the temperature of the user (orthe underlying mattress), and subsequently compare the temperaturereadings to a table or other data structure stored in memory thatcorrelates user temperature with sleep state. When the system determinesthat the user is in a certain sleep state, based on the sensedtemperature, then pressure adjustments can be made according to thepreferences previously set by the user. A similar process can be usedfor a single user or multiple users of air bed system 10.

In an example, the average temperature of one or more users can belearned over time to increase the accuracy of the sleep statedetermination. Similar to the learned pressure measurements, the learnedtemperature measurements may be taken over a learning period of a numberof days or other period (e.g., one or more weeks) to obtain averagetemperatures for the users, which can then be used as baselines forfuture sleep state determinations.

Based on one or more of the above methods of presence detection, apressure reading at a pre-set time may be grouped into either a presencepressure reading or non-presence pressure reading. Accordingly, at theend of the learning period, the pressure readings may be averaged tocome up with an “on-bed” average pressure reading and an “empty bed”pressure reading. More complex groupings may also be used. For example,for each pre-set time period there may be an “on-bed” average pressurereading and an “empty bed” pressure reading. Additional granularity mayalso be used with respect to the “on-bed” pressure readings. Forexample, different positions of a user may influence the pressurereadings. Accordingly, data processing system 400 may receive anindication as to the position of a user (e.g., on back, on side) anddetermine average pressure readings for those positions. The position ofthe user can be determined by monitoring pressure, temperature, ormotion of the user at one or more times and correlating the collecteddata with a series of user positions on the air mattress. In oneexemplary system, the position of the user can be determined bymonitoring temperature with a plurality of temperature sensors andanalyzing the user's temperature profile on the air mattress.

In various examples, the pressure level of the air mattress can bemonitored (1906). For example, after the learning period is over,pressure readings can be taken at the same times used during thelearning period or at different times. In an example, the pressure isnot monitored every day, but instead can be monitored every week, forsome other period, or at other regular or irregular intervals. Each timea pressure reading is taken, it can be compared to the pressure levelstaken during the learning period. As discussed above, the pressurereadings can be correlated with different factors. Thus, the monitoredpressure readings can be compared based on those same factors.

In some examples, when the pressure readings during the learning periodare based on times of the day, the following process may be used. At oneor more times of the day where there is a learned pressure reading, thecurrent pressure reading may be retrieved. For example, at one of thepre-set times (e.g., noon), a pressure reading may be taken. The tableor other data structure storing the learned pressure readings may beaccessed to retrieve a comparison pressure reading from one or morestored learned pressure readings for the same pre-set time. A comparisonmay then be made between the current pressure reading and the comparisonpressure reading. As discussed above, each time period may have morethan one pressure reading. In such situations, the comparison pressurereading may be the stored pressure reading that is closest to thecurrent pressure reading. In some examples, when the pressure readingsduring the learning period are based on presence of someone in the bedthe following process may be used. At one or more times of the day wherethere is a learned pressure reading, the current pressure reading may beretrieved. In addition to the pressure, the presence of a person in thebed may be determined as discussed above. Additionally or alternatively,the position of the person may be determined as also discussed above.The table or other data structure storing the learned pressure readingsmay be accessed to retrieve a comparison pressure reading based on theone or more stored learned pressure readings for the same pre-set timeand with the same presence or sleep position. A comparison may then bemade between the current pressure reading and the comparison pressurereading.

In various embodiments, instead of taking pressure readings at the sametimes as the learning period, the pressure may be monitored at differenttimes. In such scenarios, the current taken pressure reading may becompared to an average of the pressures during the learning period. Forexample, the stored pressure readings for all “empty bed” pressurereadings may be averaged to determine an average “empty bed” pressureand similarly an “on-bed” average may be calculated. Additionally, asdiscussed above more granular pressure readings may be taken withrespect to sleep cycle and sleep position. In such situations thecomparison pressure reading may be based on the time and sleep cycle orsleep position as necessary.

After the current pressure reading has been taken, a determination maybe made if the current pressure reading is out-of-range of an allowedpressure range (1908) or user pre-set pressure or firmness setting asdiscussed above. For example, a threshold may be stored on a storagedevice (e.g., computer memory 512). If the current pressure reading isfarther away from the retrieved comparison pressure+/−the threshold(e.g., either too much or too little pressure) than the current pressurereading may be considered out-of-range. A similar comparison can beperformed when using pre-set pressure or firmness settings. When it ishas been determined that the current pressure reading is within range,flow may continue back to 1906 until the next pressure reading.

In addition to monitoring the pressure of the air mattress, the sleepposition or the sleep state of the user, or both, can be monitored. Thesleep position or the sleep state of the user can help to determinewhether the pressure of the air mattress should be adjusted and theamount by which the pressure should be adjusted.

When it is has been determined that the current pressure isout-of-range, a determination may be made as to if an adjustment to theair mattress pressure should currently be made (1910). The decision maybe based on one or more factors including, but not limited to, presenceof someone on the air mattress, sleep cycle of a person, position of aperson, and time of the day. For example, user preferences for theauto-adjust feature may be retrieved to determine the global enablementpreference, presence preference, sleep cycle preference, sleep positionpreference, and time preference of the user. These preferences may becompared to the current time, presence status, sleep cycle, sleepposition, and time as appropriate to determine if the user's preferenceindicates an adjustment may be made. In addition to the user'spreferences, system preferences for the auto-adjust feature may also beretrieved (e.g., stored in computer memory 512) to determine if anadjustment should be made. In some instances, the system preferences mayalso indicate that pressure may only be decreased and not increased (orvice-versa) at certain times, sleep states, etc. When a user preferenceconflicts with a system preference, the user preference may takeprecedence. For example, if a system preference allows an adjustment at9:00 AM, but the user preference indicates no adjustments should be madebefore 10:00 AM, no adjustment should be made.

In various examples, the determination whether an adjustment to the airmattress pressure should currently be made may be subject to pre-setconditions. The pre-set conditions can dictate, for example, thatpressure changes can only be made when the user is in a certain state ofsleep (i.e., deep sleep), in a certain sleep position, or after acertain period of time. By utilizing pre-set conditions, it can bepossible to avoid making pressure changes due to potential userrestlessness or quick changes in sleep position, such as from a backposition to a side position and then again to the back position. In anexample, the data processing system 400 or another suitable componentcan operate a time-out or delay feature to ensure that the user stays inthe new sleep position for a certain period of time, thereby justifyinga pressure change in the air mattress. Numerous pre-set conditions canbe monitored and stored in memory, and the determination whether anadjustment to the air mattress pressure should be made may be subject toone or a combination of the pre-set conditions. In various examples, thepressure adjustment determination can be based solely on sleep state,solely on a time delay, or on both sleep state and a time delay. Underone exemplary scenario, the air mattress pressure can only be adjustedif the user moves from a first sleep position to a second sleep positionand either remains in the second sleep position for a specified periodof time or is detected to have fallen back into a certain sleep state,such as deep sleep.

In various examples, once it is determined that the system and userpreferences allow an adjustment to be made, a rate-of-change (e.g.,PSI/minute) may be determined to adjust the air mattress (1912) back tothe retrieved comparison pressure. For example, when it has beendetermined that a person is sleeping the rate-of-change may be lowerthan if no one is on the bed. A table or other data structure may storethe rate-of-change for the various permutations of time of day, presenceof a person, sleep cycle of a person, and position of a person. Therate-of-change may also be a series of changes rather than a continuouschange. For example, if a person is sleeping, small adjustments may bemade over the course of two hours. In contrast, if the time is noon andno one is on the bed, the pump may increase the pressure back to thecomparison pressure at the maximum rate available. In various examples,the pressure of the air mattress is adjusted at the determinedrate-of-change (1914) to the retrieved comparison pressure.

In accordance with the present disclosure, when making automaticadjustments that correspond to a change in the sleep position of theuser (i.e., a change compared to an initial or prior determined sleepposition), the adjustment can be made based upon either user pre-setpressure values, learned pressure settings, or default, pre-set pressurevalues. For example, the default, pre-set pressure values may indicate aslight reduction in the pressure of the air mattress when it has beendetected that the user has rolled from a back position or a stomachposition to a side position. In accordance with the present disclosure,when making automatic adjustments that correspond to a change in thesleep position of the user, the adjustment can also be made based uponeither user pre-set pressure values, learned pressure settings, ordefault, pre-set pressure values that correspond to the various sleeppositions.

In various examples, when it is determined an adjustment may not becurrently made, a future time may be determined to make an adjustment(1916). For example, if it is determined that the air mattress has toohigh of a pressure while a person is sleeping, and the user indicates noadjustments may be made while he or she is asleep, data processingsystem 400 may examine the user and system preferences to determine thenext time an adjustment is allowed and schedule a pressure change atthat time. For example, while the user is sleeping on the bed, the dataprocessing system 400 may determine how much of a pressure change willbe necessary when the user preferences allow for the pressureadjustment. Thus, when the user wakes up and is off of the bed, theadjustment can be viewed as time and flow based rather than pressurebased. For example, if the data processing system 400 determines thatthe pressure should be increased by 2 PSI but the user preferencesindicate that no adjustments may be made while asleep, then the systemcould wait until the user is no longer detected as present on the bedand the pump 20 could be turned on for a period of time equal to theamount of time it would have taken to increase the pressure by 2 PSIwhile the user was present on the bed.

In various examples, variations of the above method may be employedusing a set schedule. For example, scheduled pressure changes may bemade every Monday at 10:00 AM to adjust the air mattress back to anaverage pressure determined during the learning period. Then, during thenight small adjustments may be made to lower the air pressure of the airmattress as the mattress increases temperature and thus pressure. Bymaking at least one change weekly, the pressure of the air mattress maynot get too far away from the pressure the user of the air mattress isaccustomed to even if there is a mechanical failure in the air mattress.

Rather than making a change or adjustment to the pressure of the airmattress at a set time interval, such as once a week, the pressure ofthe air mattress can be constantly monitored and adjusted to maintainthe desired pressure setting. As mentioned above, external factors suchas body heat, room temperature, barometric pressure changes and the likemay cause the actual pressure of the air mattress to vary from thedesired pressure. In an example, the data processing system 400 oranother suitable component can sample one or more pressure sensors on aperiodic or constant basis to determine whether the current, actualpressure is substantially equivalent to the desired pressure at thattime. When the system detects that the current, actual pressure variesfrom the desired pressure by at least a threshold amount, then the dataprocessing system 400 may instruct the pump controller 504 to adjust thepressure of the air mattress back to the correct pressure, or within anacceptable range of the correct pressure.

As discussed above, the data processing system 400 can include atemperature controller 1006. In various examples, in addition toadjusting pressure of the air mattress in accordance with the previousexamples, the temperature controller 1006 or another suitable componentcan be programmed to increase, decrease, or maintain the temperature ofa user or the air mattress. Temperature can be sensed using any suitabletemperature sensing means as discussed above. Further, temperaturechanges can be implemented via a pad placed on top of the mattress orincorporated into the mattress itself. In various examples, air may bepushed through the pad and vented to cool off a user of the bed, and thepad may include a heating element that may be used to keep the userwarm. The temperature controller 308 can receive temperature readingsfrom the pad continuously or at select intervals.

In one example, the user can pre-select the desired temperature at oneor more times during the night (or day). Thus, based on the user'sinput, a desired temperature profile can be pre-set such that the userwill experience the desired temperature throughout a pre-defined sleepperiod. In another example, the user's sleep schedule can be “learned”using a process similar to that described above in the various pressureadjustment examples. A real time clock (“RTC”) located, for example, inthe motherboard 402 can be used during the learning process and to trackthe current time to determine when temperature adjustments should bemade.

In an example, the system could learn over a period of time that theuser typically goes to bed at 9:00 pm. Alternatively, the user couldpre-set a bed time using preferences accessible via a menu. With alearned or pre-set bed time of 9:00 pm, the temperature controller 308can initiate adjustment of the air mattress to the desired temperatureselected by the user prior to 9:00 pm, such as at about 8:30 pm. Thus,by the time the user enters the bed at about 9:00 pm, the bed will be atthe desired sleep temperature. Throughout the night the temperaturecontroller 1006 can initiate changes in temperature based on thepre-selected user input. Alternatively, upon learning the user's sleepschedule, the temperature can be automatically adjusted at specifiedtimes through the night. Sleep state can also be detected, as discussedabove, and the temperature can be adjusted based upon the user's sleepstate throughout the night. In an example, one hour before the scheduledor learned wake-up time of the user, the temperature controller 1006 canadjust the bed to a cooler temperature to help the user wake-up. Oncethe user gets out of bed, the temperature controller 308 can turn offthe pump, thermoelectric engine, or other temperature adjustment meansto allow the bed to return to a natural temperature. In an example, anyof the means referenced above for determining presence of an individualcan be used to determine when the user gets out of bed.

FIG. 20 is a flowchart of method 2000 to monitor and adjust temperatureof an air mattress, according to various examples. For labelingpurposes, and not by way of limitation, method 2000 is referred toherein as the “temperature-adjust” method or feature. While many of theoperations of method 2000 are described as being performed on dataprocessing system 400, other components may be used. For example, pumpcontroller 504 may store the preferences and determine if thetemperature-adjust feature should be engaged as further described below.In various examples, data processing system 400 acts as a relay of thepreferences.

At block 2002, in various examples, user preferences related to thetemperature-adjust method are received at data processing system 400.The preferences may be received from one or more of remotes 122, thecomputing device 414, or a cloud service 410. For example, using anapplication running on the computing device 414, a UI may be presentedto the user. This may be the same UI as discussed above with respect tothe auto-adjust feature or a different UI. The UI may include inputindicia (check boxes, radio buttons, input forms, etc.) for thepreferences related to the temperature-adjust method. A user mayinteract (e.g., click, activate) with the input indicia to set thepreferences. Similar to the preferences discussed above with respect tothe auto-adjust feature, the preferences associated with thetemperature-adjust feature may be stored in a storage device of the dataprocessing system 400 and/or be transmitted to the pump motherboard 402for storage. In various examples, the preferences may be stored in adatabase (relational, non-relational, flat file, etc.) or in astructured file (e.g., XML), for example in a cloud service 410 such asthe device manager 1210 of the bed data cloud 410 a. The preferences mayalso have default, pre-set values if the user does not input a value.

Numerous options may be selected by the user to create an optimaltemperature environment prior to falling asleep, while sleeping, andafter waking up. For example, the user can select a temperature of theair mattress prior to going to bed such that, upon entry into the bed,the temperature will be at a desired level. The user can further selectto adjust the temperature of the air mattress one or more timesthroughout the period of sleep (i.e., night) to optimize sleep quality.In an example, at a designated time prior to a scheduled wake-up, theuser can select to adjust the temperature to a desired wake-uptemperature. The wake-up temperature may be cooler than the sleepingtemperature or temperatures.

One of the preferences or options that may be selected is whether toutilize user input data related to the sleep schedule of the user or a“learning” process similar to that described above with respect to theauto-adjust feature to learn the sleep schedule of the user over alearning period.

If the user elects to input data related to the typical or desired sleepschedule of the user, the method continues at block 2004 where the usercan enter, for example, a typical sleep schedule for the user includingat least a “go to bed” time and a “wake-up” time. Furthermore, differentsleep schedules can be selected for different days of the week.

If the user elects to utilize the sleep schedule learning feature, themethod continues at block 2006 where the user's sleep schedule islearned over a period of time, such as several days or weeks.

Regardless of whether the user elects to create a manual, customizedsleep schedule or utilize the learning feature, the method continues atblock 2008 where the RTC of the control system is monitored and comparedto the manual user sleep schedule data or the learned sleep scheduledata to determine, at block 2010, when it is time for a temperatureadjustment. If it is determined that a temperature adjustment is notcurrently necessary based on the time comparison, then the method loopsback to block 2008 where the time monitoring step continues. However, ifat block 2010 it is determined that a temperature adjustment should bemade, the method continues at block 2012 where the new temperature isdetermined based on user preferences or default values (in the casewhere the user has not specified a particular temperature). Finally, themethod continues at block 2014 where the temperature of the air mattressis adjusted to the desired temperature. Once the temperature has beenadjusted to the desired temperature at block 2014, the method can returnto block 2008 to monitor for further temperature adjustments.
